THE COMPANY

      The Company is a development-stage  biopharmaceutical company dedicated to
developing and commercializing products and technologies for diagnostic imaging,
cancer  therapy and  ethical  drug  development  utilizing  peptide,  monoclonal
antibody and  radiopharmaceutical  technologies.  The Company  concentrates  its
activities in two technology  areas,  each of which the Company  believes may be
used to develop products with potential diagnostic and therapeutic applications.
These technologies  involve the Company's (i)  patent-pending  Metal Ion-induced
Distinctive  Array of Structures  ("MIDAS")  metallopeptide  technology  ("MIDAS
technology")  and  (ii)  patented  and   patent-pending   direct   radiolabeling
technology.

      The  Company  believes  that the MIDAS  technology  represents  a platform
technology which may enable the design and synthesis of novel peptide analogs or
mimics.  Further, the Company believes that its MIDAS technology may provide the
Company with the flexibility to generate its own  pharmaceutical  products,  and
the  ability  to  target  and  complement   existing   product   portfolios  and
technological  bases of other  companies.  The Company  intends to seek to enter
into  collaborative  arrangements  to assist in development,  manufacturing  and
marketing of certain proposed products

                                      1

<PAGE>



utilizing  the MIDAS  technology.   The Company  has  entered   into  a  license
option agreement as to certain proposed products based on MIDAS technology.  See
"Business -- MIDAS Technology."

      The Company is developing two proposed  products  incorporating its direct
radiolabeling  technology,  (i) LeuTech,  an infection and inflammation  imaging
product,  and (ii) PT-5,  a  radiotherapeutic  peptide  somatostatin  analog for
cancer therapy. The Company is devoting substantial efforts and resources to the
development  of LeuTech,  which the Company  believes will be its first proposed
product to enter  Company-sponsored  clinical  trials.  The Company  anticipates
seeking one or more  marketing  partners for LeuTech prior to product  approval.
See "Business --Direct Radiolabeling Technology."

      The Company is at an early stage of development  and has not yet completed
the  development  of any products  based on either its MIDAS  technology  or its
direct  radiolabeling  technology.  Accordingly,  the  Company  has not begun to
market or generate revenues from the  commercialization of any such products. It
will  be a  number  of  years,  if  ever,  before  the  Company  will  recognize
significant revenues from product sales or royalties. The Company's technologies
and products  under  development  will require  significant  time-consuming  and
costly research, development, pre-clinical studies, clinical testing, regulatory
approval and significant additional investment prior to their commercialization,
which may never occur. There can be no assurance that the Company's research and
development  programs  will be  successful,  that its products  will exhibit the
expected  biological results in humans, will prove to be safe and efficacious in
clinical  trials or will obtain the  required  regulatory  approvals or that the
Company or its  collaborators  will be successful in obtaining market acceptance
of any of the  Company's  products.  There can be no assurance  that the Company
will be  successful  in  entering  into  strategic  alliances  or  collaborative
arrangements  on  commercially  reasonable  terms,  if  at  all,  or  that  such
arrangements will be successful, or that the parties with which the Company will
establish  arrangements will perform their obligations under such  arrangements.
The Company or its collaborators  may encounter  problems and delays relating to
research and development,  regulatory approval, manufacturing and marketing. The
failure by the Company to address  successfully  such  problems and delays would
have a material adverse effect on the Company. In addition,  no assurance can be
given that  proprietary  rights of third  parties  will not preclude the Company
from  marketing  its  proposed  products or that third  parties  will not market
superior or equivalent products.

      Since  June 25,  1996,  the  effective  date of the  Company's  Merger (as
"Merger"  is  defined  in  "Business   --  History  and  Merger")   with  RhoMed
Incorporated  ("RhoMed"),  now a  wholly-owned  subsidiary  of the Company,  the
business of RhoMed has  represented  the on-going  business of the Company.  See
"Business -- History and Merger."

      The  address  of the  Company's  principal  executive  offices  is Palatin
Technologies, Inc., 214 Carnegie Center, Suite 100, Princeton, NJ 08540, and the
telephone number is (609) 520-1911.

LOSS OF THEIR ENTIRE  INVESTMENT.  EACH  PROSPECTIVE  INVESTOR  SHOULD  CONSIDER
CAREFULLY THE RISKS  INHERENT IN AND AFFECTING  BOTH THE BUSINESS OF THE COMPANY
AND THE VALUE OF THE COMMON STOCK AND  SPECULATIVE  FACTORS  INCLUDING,  WITHOUT
LIMITATION,  THE FOLLOWING RISK FACTORS, AS WELL AS OTHER INFORMATION  CONTAINED
ELSEWHERE IN THIS PROSPECTUS BEFORE MAKING AN INVESTMENT DECISION.

      EARLY  STAGE  OF   DEVELOPMENT;   UNCERTAINTY   OF  PRODUCT   DEVELOPMENT;
TECHNOLOGICAL  UNCERTAINTY.  The Company is at an early stage of development and
has not yet completed the  development of any products based on either its MIDAS
technology or its direct radiolabeling technology.  Accordingly, the Company has
not begun to market or generate revenues from the  commercialization of any such
products.  It will be a number  of  years,  if ever,  before  the  Company  will
recognize  significant  revenues from product sales or royalties.  The Company's
technologies   and  products   under   development   will  require   significant
time-consuming and costly research,  development,  preclinical studies, clinical
testing,  regulatory  approval and significant  additional  investment  prior to
their  commercialization,  which may never occur. There can be no assurance that
the Company's  research and  development  programs will be successful,  that its
products  will  exhibit  the  expected  biological  results in humans,  that its
products  will prove to be safe and  efficacious,  that its products will obtain
the  required  regulatory  approvals,  demonstrate  substantial  therapeutic  or
diagnostic benefit, be commercialized on a timely basis, experience no design or
manufacturing  problems,  be  manufactured on a large scale, or be economical to
market, or that the Company or its collaborators will be successful in obtaining
market  acceptance  of any of the  Company's  products  or  generate  sufficient
revenue to support research and development programs.  There can be no assurance
that the Company will be  successful  in entering  into  strategic  alliances or
collaborative  arrangements  on commercially  reasonable  terms, if at all, that
such arrangements will be successful, or that the parties with which the Company
will  establish   arrangements   will  perform  their   obligations  under  such
arrangements. The Company or its collaborators may encounter problems and delays
relating to research and development,  regulatory  approval,  manufacturing  and
marketing.  The failure by the Company to successfully address such problems and
delays  would have a material  adverse  effect on the Company.  In addition,  no
assurance  can be  given  that  proprietary  rights  of third  parties  will not
preclude the Company from marketing its proposed  products or that third parties
will not market superior or equivalent  products.  See "Management's  Discussion
and Analysis of Financial Condition and Results of Operations" and "Business."

      HISTORY OF  OPERATING  LOSSES AND  ACCUMULATED  DEFICIT.  The  Company has
incurred net operating losses since its inception  (January 28, 1986) and, as of
March 31, 1997, had an accumulated deficit of approximately $11.7 million, which
has increased to date. The Company anticipates  incurring additional losses over
at least the next several  years and such losses are expected to increase as the
Company  expands its research and development  activities  relating to its MIDAS
technology and its direct radiolabeling  technology.  To achieve  profitability,
the Company,  alone or with others,  must successfully  develop its technologies
and products,  conduct preclinical studies and clinical trials,  obtain required
regulatory  approvals and  successfully  manufacture,  introduce and market such
technologies  and products.  The time required to reach  profitability is highly
uncertain, and there can

                                      5

<PAGE>



be  no assurance that the  Company  will  be  able to achieve profitability on a
sustained  basis,  if at all.  See  "Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations."

      NEED FOR  ADDITIONAL  FINANCING  AND ACCESS TO  CAPITAL.  The  Company has
incurred negative cash flow from operations since its inception. The Company has
expended,  and will continue to expend in the future, if available,  substantial
funds to continue its research and development  programs,  including preclinical
studies and clinical  trials,  to seek regulatory  approval of its products,  to
develop manufacturing and marketing capabilities, and to fund the growth that is
expected to occur if any of its proposed  products  are approved for  marketing.
Further,  the Company  has  significant  long-term  debt that is due and payable
during the fiscal years ending June 30, 1998 and 1999. The Company  expects that
its existing capital  resources will be adequate to make scheduled debt payments
and to fund its  operations  through June 1998.  No assurance  can be given that
there will be no events  affecting the Company's  operations  that would deplete
available resources significantly before such time. The Company's future capital
requirements  depend  on  many  factors,  including  continued  progress  in its
research and  development  activities,  progress  with  preclinical  studies and
clinical  trials,  prosecuting and enforcing  patent claims,  technological  and
market developments, the ability of the Company to establish product development
arrangements,  the  cost  of  manufacturing  scale-up  and  effective  marketing
activities and  collaborative  or other  arrangements.  The Company will seek to
obtain additional funds through public or private  financings,  including equity
or debt financings,  collaborative or other arrangements with corporate partners
and others,  and from other sources.  No assurance can be given that  additional
financing  will be available when needed,  if at all, or on terms  acceptable to
the Company. If adequate additional funds are not available,  the Company may be
required  to  delay,  scale  back  or  eliminate  certain  of  its  research  or
development activities,  its manufacturing and marketing efforts, or require the
Company to license to third parties certain  products or  technologies  that the
Company would otherwise seek to commercialize  itself. If adequate funds are not
available,  there will be a material  and  adverse  effect on the  Company.  See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations" and "Business."

      POTENTIAL VOLATILITY OF PRICE; LOW TRADING VOLUME. The market price of the
Common Stock, like that of many other development-stage public pharmaceutical or
biotechnology  companies,  has been highly volatile and may be so in the future.
Factors such as  announcements  of  technological  innovations or new commercial
products by the Company or its competitors, disclosure of results of preclinical
and clinical testing, adverse reactions to products, governmental regulation and
approvals,  developments  in  patent  or other  proprietary  rights,  public  or
regulatory  agency  concerns  as to the  safety  of  products  developed  by the
Company, litigation and general market conditions may have a significant adverse
effect on the market price of the Common  Stock.  In addition,  in general,  the
Common Stock has been thinly traded on the Bulletin Board,  which may affect the
ability of the Company's  stockholders to sell shares of the Common Stock in the
public market.  There can be no assurance that a more active trading market will
develop in the future.  From June 26, 1996 (the date  subsequent  to the date of
the Merger) to June 30, 1997, the Company's Common Stock has traded at per share
prices  between $5 and $1 1/4. There can be no assurance that this high level of
volatility  will not  persist in the future and that  purchasers  of the Offered
Shares will not be adversely affected.  Further,  the stock market has from time
to time experienced extreme price and volume fluctuations

                                      6

<PAGE>



that may be unrelated to the operating performance of particular companies. Such
fluctuations may adversely affect the price of the Common Stock. See "Market for
Common Stock and Related Stockholder Matters."

      PATENTS  AND  PROPRIETARY   RIGHTS,  NO  ASSURANCE  OF  ENFORCEABILITY  OR
SIGNIFICANT COMPETITIVE ADVANTAGE. In general, the patent positions of companies
relying upon  biotechnology  are highly  uncertain and involve complex legal and
factual questions. To date, there has emerged no consistent policy regarding the
breadth of claims that are properly accorded to biotechnology patents. There can
be no assurance  that patents will issue from the patent  applications  filed by
the  Company or its  licensors  or that the scope of any  claims  granted in any
patent will provide meaningful proprietary protection or a competitive advantage
to the Company. There can be no assurance that the validity or enforceability of
patents  issued or licensed to the Company will not be  challenged by others or,
if challenged, will be upheld by a court. In addition, there can be no assurance
that  competitors  will not be able to circumvent any patents issued or licensed
to the Company.  In the United  States,  patent  applications  are maintained in
secrecy  until  they  issue as  patents,  and thus  publications  in the  patent
literature lag behind actual discoveries. Scientific publications also generally
appear  after a patent  application,  if any,  is filed.  As a result of delayed
publication, the Company cannot be certain that its scientists were the first to
make inventions covered by its patents and patent applications.

      In the event another party has also filed a patent application relating to
an  invention  claimed  in a Company  patent  application,  the  Company  may be
required to participate in an interference  proceeding adjudicated by the United
States  Patent and  Trademark  Office to determine  priority of  invention.  The
possibility  of  an   interference   proceeding   could  result  in  substantial
uncertainties  and  cost  for the  Company,  even  if the  eventual  outcome  is
favorable to the Company.  An adverse outcome could result in the Company losing
patent  protection for the subject of the  interference,  subject the Company to
significant  liabilities  to third  parties  and  require  the Company to obtain
license  rights from third  parties at  undetermined  cost or to cease using the
technology.

      While no valid patent that would be infringed by manufacture,  use or sale
of the Company's proposed products has come to the attention of the Company, the
Company's  proposed  products are still in the  development  stage,  and neither
their  formulations  nor their method of  manufacture  is  finalized.  Moreover,
patents  the claims of which  would be  infringed  by the  Company's  commercial
activities  may not have issued as yet.  There can thus be no assurance that the
manufacture,  use or sale of the Company's  proposed  products will not infringe
patent rights of others.  The Company may be unable to avoid infringement of any
such patents and may have to seek a license,  defend an infringement  action, or
challenge the validity of such patents in court.  There can be no assurance that
a license will be available to the Company, if at all, upon terms and conditions
acceptable  to the  Company  or that the  Company  will  prevail  in any  patent
litigation.  Patent litigation is costly and time consuming, and there can be no
assurance  that the  Company  will have  sufficient  resources  to  pursue  such
litigation.  If the Company does not obtain a license under any such patents, is
found liable for infringement, or is not able to have them declared invalid, the
Company may be liable for significant money damages,  may encounter  significant
delays in bringing products to market, or may be precluded from participating in
the manufacture, use or sale of products or methods of treatment covered by such
patents.

                                      7

<PAGE>



      The Company relies substantially in its product development  activities on
certain  technologies  which are  neither  patentable  nor  proprietary  and are
therefore potentially available to the Company's  competitors.  The Company also
relies on certain  proprietary  technologies  (trade secrets and know-how) which
are not  patentable.  Although  the  Company  has  taken  steps to  protect  its
unpatented   trade   secrets  and   know-how,   in  part   through  the  use  of
confidentiality  agreements  with its employees,  consultants and certain of its
contractors,  there  can be no  assurance  that  these  agreements  will  not be
breached,  that the Company would have adequate  remedies for any breach or that
the Company's trade secrets will not otherwise  become known or be independently
developed or discovered by competitors.  If the Company's employees,  scientific
consultants or collaborators develop inventions or processes  independently that
may be applicable to the Company's product candidates,  disputes may arise about
ownership  of  proprietary  rights  to  those  inventions  and  processes.  Such
inventions and processes will not necessarily become the Company's property, but
may remain the  property of those  persons or their  employers.  Protracted  and
costly  litigation  could be necessary to enforce and determine the scope of the
Company's  proprietary  rights.  Failure to obtain or maintain  patent and trade
secret protection,  for any reason,  could have a material adverse effect on the
Company.

      Certain of the Company's patents are directed to inventions developed with
funds from United States  government  agencies or within  academic  institutions
from which the Company earlier  acquired rights to such patents.  As a result of
these  arrangements,  the United  States  government  may have rights in certain
inventions  developed  during the course of the performance of federally  funded
projects as required by law or agreements with the funding agency.

      Several bills  affecting  patent rights have been introduced in the United
States  Congress.  These bills address various aspects of patent law,  including
publication of pending  patent  applications,  modification  of the patent term,
re-examination, subject matter and enforceability. It is not certain whether any
of these bills will be enacted  into law and  whether,  as  enacted,  they would
affect  the  scope,  validity  and  enforceability  of  the  Company's  patents.
Accordingly,  the effect of  legislative  change on the  Company's  intellectual
property estate is uncertain. See "Business."

      UNCERTAINTY OF DEVELOPMENT OF MIDAS TECHNOLOGY.  The Company is engaged in
research  and  development  on a number of product  opportunities  for its MIDAS
technology,  including use as a thrombosis  imaging agent, an infection  imaging
agent and an  immunostimulatory  agent,  and believes that MIDAS  technology may
have medical  applications in a variety of areas,  including  immune  disorders,
cancers and  cardiology.  The Company intends to expand research and development
of MIDAS technology  applications  primarily  through  strategic  alliances with
other  entities.  No assurances can be made regarding the  establishment  or the
timing of such  alliances,  and the failure to  establish  such  alliances  on a
timely basis could limit the Company's  ability to develop MIDAS  technology and
could have a material  adverse  effect on the  Company.  The Company  expects to
devote  resources to expand research and development of MIDAS  technology to the
extent funding is available.  No prediction can be made,  however, as to when or
whether the areas in which there are ongoing MIDAS technology  research projects
will yield scientific  discoveries,  or whether such research projects will lead
to commercial products. See "Business."

      While the Company has entered into a License Option Agreement (the "Option
Agreement") with Nihon Medi-Physics Ltd. ("Nihon"),  pursuant to which Nihon has
an option to exclusively

                                      8

<PAGE>



license certain products based on the Company's MIDAS  technology,  there can be
no assurance that future payments  provided for in the Option  Agreement will be
made,  that the  Company  and Nihon will ever enter  into a  definitive  license
agreement, or that a definitive strategic alliance between the Company and Nihon
will result in the development or commercialization of any product. In the event
that Nihon gives notice of its right to negotiate a license  agreement,  and the
parties  cannot  agree on terms of such license  agreement,  the Company will be
required to repay  certain  monies to Nihon.  Failure to enter into a definitive
license agreement,  or being required to repay certain monies to Nihon, may have
a  material  adverse  effect on the  Company.  See  "Management  Discussion  and
Analysis of Financial Condition and Results of Operations" and "Business."

      UNCERTAINTY  OF  DEVELOPMENT  OF LEUTECH.  The Company has entered into an
exclusive  license  agreement  with The Wistar  Institute of Anatomy and Biology
("Wistar  Institute")  for a defined field of use for the antibody and cell line
used for LeuTech, which license agreement contains certain performance criteria.
Failure to meet the  performance  criteria  for any reason or any other event of
default  under the license  agreement  leading to  termination  of the exclusive
license  agreement with Wistar Institute would have a material adverse effect on
the  Company.   While  the  Company  has  negotiated  a  long-term   contractual
arrangement for the manufacture of the purified antibody  necessary for LeuTech,
there can be no  assurance  that such  contractor  will be able to  successfully
manufacture  purified  antibody  for  LeuTech on a  sustained  basis,  that such
contractor  will  remain in the  contract  manufacturing  business  for the time
required by the  Company,  or that the  Company  will be able to enter into such
contractual   arrangements  as  to  other  steps  and  components   required  to
manufacture  LeuTech.  Such  manufacture  must be done under good  manufacturing
practice  ("GMP")  requirements  prescribed  by the United  States Food and Drug
Administration ("FDA") and other governmental agencies. To date, the Company has
only manufactured  LeuTech in lots preparatory to initiating clinical trial use,
and has not determined  whether  commercial  quantities of LeuTech in conformity
with these  standards can be  manufactured on a sustained basis at an acceptable
cost.

      While the Company intends to file an Investigational  New Drug Application
("IND")  on  LeuTech  with  the  FDA  on one  or more  selected  indications  in
the second half of 1997,  and to  complete  Phase III  clinical  trials and file
regulatory applications to market with the FDA in the second half of 1998, there
can be no  assurance  that the  Company's  LeuTech  development  program will be
successful,  that the FDA will permit the Company's  planned  clinical trials to
proceed,  that LeuTech will prove to be safe and efficacious in clinical trials,
that  LeuTech can be  manufactured  in  commercially  required  quantities  on a
sustained  basis at an acceptable  price,  that LeuTech will obtain the required
regulatory approvals or that the Company or its collaborators will be successful
in obtaining market acceptance of LeuTech.  The Company or its collaborators may
encounter  problems and delays relating to research and development,  regulatory
approval,  manufacturing  and marketing of LeuTech.  Failure to develop,  obtain
regulatory approval for,  manufacture and market LeuTech on a timely basis would
have a material adverse effect on the Company. See "Business."

      UNCERTAINTY OF  DEVELOPMENT  OF PT-5.  The Company is discussing  entering
into  a  collaborative  arrangement  with  a  third  party  to  use  a  specific
somatostatin analog for PT-5. There can be no assurance that the Company will be
able to enter into a collaborative  arrangement on acceptable  terms, if at all.
If the Company cannot conclude such arrangement, the Company will either abandon
PT-5 development or seek to develop a substitute using MIDAS technology. There

                                      9

<PAGE>



can be no assurance  that the Company will be able to enter into an  arrangement
with another party on  acceptable  terms if at all, or will be able to develop a
substitute  using MIDAS  technology  in a reasonable  period of time, or at all.
There can be no assurance  that the Company's PT-5  development  program will be
successful,  that PT-5 will exhibit the expected  biological  results in humans,
that PT-5 will prove to be safe and  efficacious  in clinical  trials,  that the
Company  will obtain the required  regulatory  approvals  for PT-5,  or that the
Company or its  collaborators  will be successful in obtaining market acceptance
of PT-5.  The Company or its  collaborators  may  encounter  problems and delays
relating to research and development,  regulatory  approval,  manufacturing  and
marketing of PT-5.

      In addition,  PT-5 requires a source of  radioactive  rhenium,  preferably
rhenium-188.  This isotope can be produced by a variety of methods,  including a
generator system;  however,  clinical grade radioactive rhenium is not currently
available  in the  United  States.  The  Company  is  aware  of an  experimental
generator   system  developed  in  the  United  States  by  Oak  Ridge  National
Laboratory, and an additional experimental generator system available in Europe.
The Company does not intend to seek to  commercialize  any source of radioactive
rhenium,  but is aware of other companies  seeking to commercialize  radioactive
rhenium.  There can be no assurance  that,  regardless  of the status of product
development by the Company, any acceptable form of radioactive rhenium will ever
be commercially  available in the United States or other countries at acceptable
prices,  if at all,  in which  event the Company may never be able to develop or
commercialize PT-5. See "Business."

      GOVERNMENT  REGULATION;  NO  ASSURANCE  OF  PRODUCT  APPROVAL.   Research,
development,  testing, clinical trials, manufacture,  distribution,  advertising
and marketing,  including distribution and sale, of pharmaceutical  products are
subject to extensive regulation by governmental authorities in the United States
and other  countries.  Prior to marketing,  proposed  products  developed by the
Company must undergo an extensive  regulatory  approval  process required by the
FDA and by comparable agencies in other countries.  This process, which includes
preclinical  studies and clinical  trials of each proposed  product to establish
safety  and  effectiveness  and  confirmation  by the FDA that good  laboratory,
clinical  and  manufacturing   practices  were  maintained  during  testing  and
manufacturing,  can take many years,  requires the  expenditure  of  substantial
resources  and  gives  larger  companies  with  greater  financial  resources  a
competitive  advantage  over the Company.  To date,  no proposed  product  being
evaluated by the Company has been  submitted for approval or approved by the FDA
or any other regulatory  authority for marketing,  and there can be no assurance
that any such product  will ever be submitted or approved for  marketing or that
the Company will be able to obtain the labeling claims desired for its products.
The  Company is and will  continue to be  dependent  upon the  laboratories  and
medical  institutions  conducting its preclinical studies and clinical trials to
maintain both good  laboratory and good clinical  practices.  Data obtained from
preclinical  studies and clinical trials are subject to varying  interpretations
which  could  delay,  limit  or  prevent  FDA  regulatory  approval.  Delays  or
rejections may be encountered based upon changes in FDA policy for drug approval
during the period of development and FDA regulatory review.  Similar delays also
may be encountered in foreign countries.

      There can be no assurance  that FDA or other  regulatory  approval for any
products  developed by the Company will be granted on a timely basis, if at all.
Delay  in  obtaining  or  failure  to  obtain  such  regulatory  approvals  will
materially adversely affect the introduction and marketing of any products which
may be developed by the Company as well as the Company's results of operations.

                                      10

<PAGE>



      When and if approvals are granted,  the Company,  the approved  drug,  the
manufacture of such drug and the  facilities in which such drug is  manufactured
are subject to ongoing  regulatory  review.  Subsequent  discovery of previously
unknown  problems may result in  restriction on a product's use or withdrawal of
the product from the market. Adverse government regulation that might arise from
future  legislative  or  administrative  action,  particularly  as it relates to
health care reform and product pricing, cannot be predicted. See "Business."

      NO COMMERCIAL  MANUFACTURING  CAPABILITY OR EXPERIENCE.  To be successful,
the Company's  products must be manufactured in commercial  quantities under GMP
requirements  prescribed by the FDA and at acceptable costs. The Company has not
yet  manufactured  any  pharmaceutical  products in  commercial  quantities  and
currently does not have the facilities to manufacture any products in commercial
quantities  under  GMP.  In the event the  Company  determines  to  establish  a
manufacturing facility, it will require substantial additional funds, the hiring
and retention of significant  additional personnel and compliance with extensive
regulations  applicable  to such a facility.  The Company has no  experience  in
commercial pharmaceutical manufacturing,  and there can be no assurance that the
Company  will  be  able  to  establish  such a  facility  successfully  and,  if
established,  that  it  will  be able  to  manufacture  products  in  commercial
quantities for sale at competitive  prices. If the Company determines to rely on
collaborators,   licensees  or  contract   manufacturers   for  the   commercial
manufacture  of its  products,  the Company will be dependent on such  corporate
partners or other  entities for, and will have only limited  control  over,  the
commercial  manufacturing  of its  products.  While the Company has entered into
manufacturing arrangements as to certain portions of the manufacture of LeuTech,
there can be no assurance that the contract  manufacturer will perform as agreed
or will remain in the contract  manufacturing  business for the time required by
the Company,  or that the Company will be able to enter into such  manufacturing
arrangements as to remaining  portions of the manufacture of LeuTech.  There can
be no  assurance  that  the  Company  will  be  able  to  enter  into  any  such
manufacturing  arrangements  as to its other  proposed  products  on  acceptable
terms, if at all. See "Business."

      LIMITED CLINICAL TRIAL EXPERIENCE.  Before obtaining  required  regulatory
approvals for the  commercial  sale of its proposed  products,  the Company must
demonstrate  through clinical trials that such products are safe and efficacious
for use. The Company is in various stages of testing,  but has not yet filed any
IND applications.  The initiation and completion of clinical trials is dependent
upon many factors,  including FDA  acquiescence,  the  availability of qualified
clinical  investigators  and access to suitable patient  populations.  Delays in
initiating and completing  clinical  trials may result in increased  trial costs
and delays in FDA submissions, which could have a material adverse effect on the
Company. To date, the Company has very limited experience in conducting clinical
trials.  The Company  will  either  need to rely on third  parties to design and
conduct any required  clinical  trials or expend  resources  to hire  additional
personnel to administer such clinical trials. There can be no assurance that the
Company  will be able to find  appropriate  third  parties to design and conduct
clinical  trials  or  that it will  have  the  resources  to hire  personnel  to
administer clinical trials in-house.

      A number of companies in the biotechnology and  pharmaceutical  industries
have  suffered  significant  setbacks in  clinical  trials,  even after  showing
promising  results in earlier studies or trials.  There can be no assurance that
the Company will not encounter  problems in its clinical  trials that will cause
the Company to delay or suspend its clinical trials, that the clinical trials of
its proposed

                                      11

<PAGE>



products will be completed at all, that such testing will ultimately demonstrate
the safety or efficacy of such proposed  products or that any proposed  products
will  receive  regulatory  approval  on a timely  basis,  if at all. If any such
problems occur, there would be a material adverse effect on the Company.
See "Business."

      LIMITED  MARKETING,  DISTRIBUTION OR SALES CAPABILITY AND EXPERIENCE.  The
Company has limited experience in marketing pharmaceutical  products,  including
distribution and selling of pharmaceutical  products, and will have to develop a
sales force and/or rely on  collaborators  or licensees or on arrangements  with
others to provide for the  marketing,  distribution,  and sales of its  proposed
products.  There can be no assurance  that the Company will be able to establish
marketing,  distribution and sales  capabilities or make arrangements with third
parties to perform such activities on acceptable terms,  which may result in the
lack of control by the Company over the marketing, distribution and sales of its
proposed  products.  In addition,  there can be no assurance that the Company or
any third party will be  successful in  marketing,  distributing  or selling any
products.  Furthermore,  the Company will compete with many other companies that
currently  have  extensive and  well-funded  marketing,  distribution  and sales
operations. See "Business."

      COMPETITION. The biopharmaceutical and radiopharmaceutical  industries are
highly competitive.  In the  biopharmaceutical  industry,  there are a number of
companies developing peptide-based drugs, including companies exploring a number
of different  approaches to making  conformationally-constrained  short peptides
for use as therapeutic  drugs. In the  radiopharmaceutical  industry,  there are
several  companies  devoted to development and  commercialization  of monoclonal
antibody-based  products and  peptide-based  products.  The Company is likely to
encounter  significant   competition  with  respect  to  its  proposed  products
currently under development. Many of the Company's competitors which are engaged
in  the   biopharmaceutical   field,   and  in  particular  the  development  of
peptide-based  products,  have substantially greater financial and technological
resources and marketing  capabilities than the Company,  and have  significantly
greater   experience  in  research  and  development.   Many  of  the  Company's
competitors  which  are  engaged  in  the  radiopharmaceutical   field,  and  in
particular the development of antibody- and peptide-based products, have greater
financial  and  technological  resources  and  marketing  capabilities  than the
Company, and have significantly  greater experience in research and development.
Accordingly,  the Company's  competitors may succeed in developing  products and
underlying  technologies  more  rapidly  than  the  Company,  and in  developing
products  that are more  effective  and useful and are less costly than any that
may be  developed  by the  Company,  and may  also be more  successful  than the
Company in  manufacturing  and marketing such products.  Academic  institutions,
hospitals,   governmental   agencies  and  other  public  and  private  research
organizations are also conducting research and seeking patent protection and may
develop competing products or technologies on their own or through collaborative
arrangements.

      The Company is aware of at least one company  developing an antibody-based
product which may compete with LeuTech as to certain indications,  which product
is marketed in certain European  countries and for which regulatory  approval is
pending  in the United  States.  The  Company  is also aware of another  company
developing  a  peptide-based  product  which may also compete with LeuTech as to
certain indications. The Company is aware of a number of companies developing

                                      12

<PAGE>



technologies  relating to the use of  peptides as drugs,  including a variety of
different approaches to making  conformationally-constrained short peptides. See
"Business."

      The Company is pursuing areas of product development in which there is the
potential for extensive technological  innovation in relatively short periods of
time.  Rapid  technological  change or  developments by others may result in the
Company's proposed products becoming obsolete or noncompetitive.

      DEPENDENCE ON THIRD-PARTY REIMBURSEMENT. Successful sales of the Company's
proposed  products in the United States and other  countries  will depend on the
availability  of  adequate   reimbursement   from  third-party  payors  such  as
governmental  entities,  managed care organizations and private insurance plans.
Reimbursement  by a  third-party  payor  may  depend  on a  number  of  factors,
including  the  payor's  determination  that  use  of  a  product  is  safe  and
efficacious,  neither  experimental nor  investigational,  medically  necessary,
appropriate  for the specific  patient and cost effective.  Since  reimbursement
approval is required from each payor  individually,  seeking such approvals is a
time-consuming   and  costly  process.   Third-party   payors   routinely  limit
reimbursement  coverage and in many instances are exerting  significant pressure
on medical  suppliers to lower their prices.  There is  significant  uncertainty
concerning  third-party  reimbursement for the use of any pharmaceutical product
incorporating  new  technology,  and  there  is no  assurance  that  third-party
reimbursement  will be available for the Company's  proposed  products,  or that
such reimbursement,  if obtained, will be adequate. Less than full reimbursement
by governmental and other  third-party  payors for the Company's  products would
adversely  affect the market  acceptance of these products and would also have a
material  adverse  effect on the  Company.  Further,  health care  reimbursement
systems  vary from  country  to  country,  and there  can be no  assurance  that
third-party  reimbursement  will be made  available for the  Company's  proposed
products under any other reimbursement system.
See "Business."

      HEALTH CARE REFORM.  The health care  industry is  undergoing  fundamental
change in the United States as a result of economic,  political  and  regulatory
influences.  There exists a powerful trend toward managed care that is motivated
by a desire to reduce costs and prices of health care.  The Company  anticipates
that the  health  care  industry,  particularly  insurance  companies  and other
third-party  payors,  will  continue to promote  cost  containment  measures and
alternative  health care delivery systems,  and political debate of these issues
will most likely  continue.  The Company cannot  predict which specific  reforms
will be proposed or adopted by industry or government or the precise effect that
such  proposals or adoption  may have on the Company.  There can be no assurance
that health care reform  initiatives  will not have a material adverse effect on
the Company.

      CONDUCTING  BUSINESS ABROAD.  To the extent the Company conducts  business
outside the United  States,  it may do so through  licenses,  joint  ventures or
other contractual arrangements for the development,  manufacturing and marketing
of its proposed  products.  No  assurance  can be given that the Company will be
able to establish suitable  arrangements,  that the necessary foreign regulatory
approvals  for its  proposed  product  will be  obtained,  that  foreign  patent
coverage will be available or that the development and marketing of its proposed
products through such licenses, joint ventures or other contractual arrangements
will be  successful.  The Company might also have greater  difficulty  obtaining
proprietary  protection for its proposed  products and technologies  outside the
United States

                                      13

<PAGE>



and  enforcing  its  rights  in  foreign  courts.   Furthermore,   international
operations  and  sales  may  be  limited  or  disrupted  by  the  imposition  of
governmental   controls   regulation  of  medical   products,   export   license
requirements,  political  instability,  trade restrictions,  changes in tariffs,
exchange  rate   fluctuations   and   difficulties  in  managing   international
operations.

      RISK OF LIABILITY; ADEQUACY OF INSURANCE COVERAGE; RISK OF PRODUCT RECALL.
The  Company's  business may be affected by potential  product  liability  risks
which are  inherent in the  testing,  manufacturing  and  marketing  of proposed
pharmaceutical  products  to be  developed  by  the  Company.  There  can  be no
assurance  that  product  liability  claims  will not be  asserted  against  the
Company, its collaborators or licensees.  The use of proposed products developed
by the  Company in  clinical  trials and the  subsequent  sale of such  proposed
products is likely to cause the Company to bear all or a portion of those risks.
Such litigation claims could have a material adverse effect on the Company.  The
Company  has  liability  insurance  providing  up  to  $1,000,000  coverage  per
occurrence  and in the aggregate as to certain  clinical  trial risks,  and will
seek   to   obtain   additional   product   liability   insurance   before   the
commercialization  of its  products.  There can be no assurance,  however,  that
insurance  will be available to the Company on acceptable  terms,  if at all, or
that such  coverage  once  obtained  would be  adequate  to protect  the Company
against  future  claims or that a medical  malpractice  or other claim would not
materially  and  adversely  affect  the  Company.  Furthermore,  there can be no
assurance  that any  collaborators  or  licensees  of the Company  will agree to
indemnify the Company, be sufficiently insured or have a net worth sufficient to
satisfy any such product liability  claims. In addition,  products such as those
proposed  to be sold by the  Company  may be subject  to recall  for  unforeseen
reasons. Such a recall could have a material adverse effect on the Company.
See "Business."

      DEPENDENCE ON KEY MANAGEMENT AND QUALIFIED  PERSONNEL;  LIMITED PERSONNEL;
DEPENDENCE ON CONTRACTORS.  The Company is highly  dependent upon the efforts of
its  management.  The loss of the services of one or more members of  management
could impede the achievement of development  objectives.  Due to the specialized
scientific  nature  of the  Company's  business,  the  Company  is  also  highly
dependent  upon its  ability to  attract  and retain  qualified  scientific  and
technical personnel. There is intense competition for qualified personnel in the
areas of the Company's activities and there can be no assurance that the Company
can presently,  or will be able to continue to, attract and retain the qualified
personnel  necessary  for  the  development  of its  existing  business  and its
expansion into areas and activities requiring additional expertise. In addition,
the Company's  intended or possible  growth and expansion  into areas  requiring
additional  skill  and  expertise,  such  as  marketing,   including  sales  and
distribution,  will require the  addition of new  management  personnel  and the
development of additional expertise by existing management  personnel.  The loss
of, or failure to recruit,  scientific,  technical and marketing and  managerial
personnel could have a material adverse effect on the Company.  See "Management"
and "Business."

       The Company relies, in substantial  part, and for the foreseeable  future
will rely, on certain  independent  organizations,  advisors and  consultants to
provide certain services,  including substantially all aspects of manufacturing,
regulatory approval and clinical management.  There can be no assurance that the
services of independent organizations, advisors and consultants will continue to
be available  to the Company on a timely basis when needed,  or that the Company
could find  qualified  replacements.  The  Company's  advisors  and  consultants
generally sign agreements that

                                      14

<PAGE>



provide for confidentiality of the Company's proprietary  information.  However,
there  can be no  assurance  that  the  Company  will be able  to  maintain  the
confidentiality  of the Company's  technology,  the dissemination of which could
have a material adverse effect on the Company.

      HAZARDOUS  MATERIALS;   COMPLIANCE  WITH  ENVIRONMENTAL  REGULATIONS.  The
Company's  research and  development  involves the  controlled  use of hazardous
materials,  chemicals and various  radioactive  compounds.  Although the Company
believes that its safety procedures for handling and disposing of such materials
comply with the standards  prescribed by federal,  state and local  regulations,
the risk of accidental  contamination  or injury from these materials  cannot be
completely  eliminated.  In the event of such an accident,  the Company could be
held liable for any damages that result and any such liability  could exceed the
resources of the Company. The Company may incur substantial costs to comply with
environmental  regulations if the Company develops  manufacturing  capacity.  In
addition,  there can be no assurance that current or future  environmental laws,
rules,  regulations  or policies will not have a material  adverse effect on the
Company.

      SHARES  ELIGIBLE FOR FUTURE SALE;  EFFECT ON ABILITY TO RAISE CAPITAL.  Of
the  12,164,444  shares of  Common  Stock  outstanding,  11,282,691  are  freely
tradable, and are not subject to any restrictions,  either under securities laws
or under lock-up or other agreements.  Additional Common Stock, including shares
issuable  upon  exercise of options  and the  outstanding  warrants,  may become
eligible  for  sale in the  public  market  from  time  to  time in the  future.
Currently,  warrants to purchase  2,775,409 shares of Common Stock or securities
convertible  into Common Stock, at prices ranging from $.05 to $70.50 per share,
with an average weighted price of $1.70 per share, are outstanding,  and options
to purchase  3,352,505  shares of Common Stock,  at prices  ranging from $.05 to
$90.00  per  share,  with an  average  weighted  price of $2.00 per  share,  are
outstanding.  The total  number of the  Offered  Shares  is  14,266,197  shares.
Furthermore,  the Company may file one or more  registration  statements on Form
S-8 to  register  shares  of  Common  Stock  available  for  issuance  under the
Company's  1996 Stock Option Plan,  and certain  other option grants and options
assumed by the Company in the Merger. Many of the foregoing options and warrants
are likely to be  exercised  at a time when the Company  might be able to obtain
additional  equity  capital on more  favorable  terms.  While those  options and
warrants  are  outstanding,  they may  adversely  affect  the terms on which the
Company could obtain  capital.  The Company cannot  predict the effect,  if any,
that market sales of Common Stock,  the exercise of options or warrants,  or the
availability  of such  Common  Stock  for sale  will  have on the  market  price
prevailing  from time to time.  Furthermore,  certain  holders of the  Company's
securities  have the right to cause the Company to register  their  Common Stock
under the Securities  Act in the future,  which could cause the Company to incur
substantial  expense,  could affect the  Company's  ability to raise capital and
also  materially  and  adversely  affect  the  prevailing  market  price  of the
Company's Common Stock.

      ANTI-TAKEOVER  CONSIDERATIONS.   The  Company's  Restated  Certificate  of
Incorporation,  as amended (the "Certificate of  Incorporation"),  authorize the
issuance of up to 2,000,000  shares of preferred stock, par value $.01 per share
("Preferred  Stock"),  of which 264,000 are authorized for issuance as shares of
Series A  Convertible  Preferred  Stock.  The  Company  is  seeking  stockholder
approval to  increase  the  authorized  number of shares of  preferred  stock to
10,000,000  shares.  See  "Description  of  Securities."  The Company's Board of
Directors has the authority,  without action by the Company's  stockholders,  to
issue shares of preferred stock, and to fix the rights and preferences

                                      15

<PAGE>



of such  preferred  stock,  except as limited in the  Certificate of Designation
relating to the Series A Convertible Preferred Stock. Accordingly,  the Board of
Directors is empowered,  without stockholder  approval, to issue a new series of
preferred stock with dividend,  liquidation,  conversion, voting or other rights
which could adversely  affect the voting power or other rights of the holders of
Common Stock. Such authority,  together with certain  provisions of Delaware law
and of the  Company's  Certificate  of  Incorporation  and bylaws,  may have the
effect of delaying,  deterring or preventing a change in control of the Company,
may discourage bids for the Company's  Common Stock at a premium over the market
price and may adversely affect the market price, and the voting and other rights
of the  holders,  of the  Common  Stock.  Although  the  Company  has no present
intention to issue any  additional  shares of its  preferred  stock,  other than
those already  authorized  for issuance  upon  exercise of the  Preferred  Stock
Placement Warrants, there can be no assurance that the Company will not do so in
the future.

     NO DIVIDENDS.  The Company has not paid cash  dividends on its Common Stock
since its inception and does not intend to pay any dividends on its Common Stock
in the  foreseeable  future.  The  Series A  Convertible  Preferred  Stock has a
dividend  preference.  See  "Market  for Common  Stock and  Related  Stockholder
Matters" and "Description of Securities."

      EQUITY  DILUTION.   Purchasers  of  the  Offered  Shares  will  experience
immediate and substantial  dilution of their  investment with respect to the net
tangible book value per share of Common Stock.

      POTENTIAL CONVERSION PRICE RESET OF SERIES A CONVERTIBLE  PREFERRED STOCK.
In 1997, the Company  consummated  an offering of units  consisting of shares of
Series A Convertible Preferred Stock. The 137,780 shares of Series A Convertible
Preferred  Stock sold in the  offering,  and the  13,778  shares  issuable  upon
exercise of the Preferred  Stock Placement  Warrants,  are  convertible,  at the
option of the holders,  into shares of Common  Stock,  at a conversion  price of
$1.24  and  stated  value of $100 per share of  Series A  Convertible  Preferred
Stock.  The conversion price is subject to a reset upon the happening of certain
events. Any reset of the conversion price applicable to the Series A Convertible
Preferred  Stock would  result in the  issuance of  additional  shares of Common
Stock upon  conversion of the Series A Convertible  Preferred  Stock,  and would
have a dilutive effect on purchasers of the Offered Shares. The conversion price
is also subject to adjustment under certain  circumstances.  See "Description of
Securities."

      CERTAIN  INTERLOCKING  RELATIONSHIPS;  POTENTIAL  CONFLICTS  OF  INTEREST.
Certain of the  directors  of the  Company  are  officers  or  directors  of the
Placement Agent or of Paramount  Capital  Investments,  LLC ("Paramount  Capital
Investments").  Paramount Capital Investments is a merchant bank specializing in
biotechnology  companies.  In the  regular  course  of its  business,  Paramount
Capital Investments identifies,  evaluates and pursues investment  opportunities
in  biomedical  and   pharmaceutical   products,   technologies  and  companies.
Generally,  Delaware  corporate law requires that any  transactions  between the
Company and any of its affiliates be on terms that,  when taken as a whole,  are
substantially  as favorable to the Company as those then  reasonably  obtainable
from  a  person  who  is  not  an  affiliate  in  an  arms-length   transaction.
Nevertheless,  neither  Paramount  Capital  Investments  nor any other person is
obligated  pursuant to any agreement or  understanding  with the Company to make
any additional products or technologies  available to the Company, and there can
be no assurance,  and purchasers of the Common Stock should not expect, that any
biomedical or

                                      16

<PAGE>



pharmaceutical product or technology identified by Paramount Capital Investments
or any other  person in the future will be made  available  to the  Company.  In
addition,  certain of the officers,  directors,  consultants and advisors to the
Company  may from time to time  serve as  officers,  directors,  consultants  or
advisors to other biopharmaceutical or biotechnology companies.  There can be no
assurance  that such other  companies  will not in the future have  interests in
conflict with those of the Company. See "Management,"  "Principal  Stockholders"
and "Certain Transactions."

      CONTROL BY OFFICERS,  DIRECTORS, AND EXISTING STOCKHOLDERS.  The Company's
executive  officers,  directors,  five percent (5%)  stockholders and affiliated
entities together may be deemed to own beneficially  approximately  35.7% of the
outstanding shares of the Common Stock, to own beneficially  approximately 18.2%
of the outstanding  shares of the Series A Convertible  Preferred Stock, to hold
approximately  22.9% of the voting  power based on stock  outstanding  as of the
date  of  this  Prospectus,  and to  hold  options  or  warrants  to  acquire  a
significant  additional  number of shares of Common  Stock.  As a result,  these
stockholders,  acting  together,  will be able to  influence  significantly  and
control  most matters  requiring  approval by the  stockholders  of the Company,
including the election of directors.  Such a concentration of ownership may have
the  effect of  delaying  or  preventing  a change in  control  of the  Company,
including  transactions in which  stockholders might otherwise receive a premium
for  their  shares  over then  current  market  prices.  Such  stockholders  may
influence corporate actions,  including  influencing  elections of directors and
significant corporate events.

      RISKS OF LOW-PRICED STOCK;  EFFECT OF "PENNY STOCK" RULES ON LIQUIDITY FOR
THE COMPANY'S  SECURITIES.  Rule 15g-9 under the Exchange Act imposes additional
sales practice  requirements on broker-dealers which sell securities meeting the
definition of a "penny stock" to persons  other than  established  customers and
"accredited  investors"  (generally,  individuals  with a net worth in excess of
$1,000,000 or annual incomes exceeding  $200,000 or $300,000 together with their
spouses and certain  institutional  entities).  For transactions covered by this
Rule, a  broker-dealer  must make a special  suitability  determination  for the
purchaser and have received the  purchaser's  written consent to the transaction
prior to sale. Consequently,  such Rule affects the ability of broker-dealers to
sell the Company's  securities  and may affect the ability of purchasers in this
Offering  to sell any of the Offered  Shares  acquired  hereby in the  secondary
market. By regulation "penny stock" is defined as any equity security that has a
market  price  (as  therein  defined)  of less  than  $5.00 per share or with an
exercise  price of less than  $5.00 per  share and is not  listed on a  national
securities exchange or quoted on the National  Association of Securities Dealers
Automated Quotation System ("Nasdaq"),  subject to certain  exceptions.  For any
transaction  involving a penny stock, unless exempt, the rules require delivery,
prior to any transaction in a penny stock, of a disclosure  schedule relating to
the penny  stock  market.  Disclosure  is also  required  to be made about sales
commissions payable to both the broker-dealer and the registered  representative
and current  quotations  for the  securities.  Finally,  monthly  statements are
required to be sent disclosing recent price information for the penny stock held
in the account and  information on the limited market in penny stock.  There can
be no assurance  that the Common Stock will qualify for exemption from the penny
stock  restrictions in the foreseeable  future. In any event, even if the Common
Stock were exempt from such  restrictions,  the Company would remain  subject to
Section  15(b)(6) of the Exchange Act,  which gives the Commission the authority
to restrict any person from  participating  in a distribution of penny stock, if
the Commission

                                      17

<PAGE>



finds  that such a  restriction  would be in the  public  interest.  The  market
liquidity for the Common Stock is materially  adversely affected by the rules on
penny stocks.

      RISK  OF  LOSS  IN  LAWSUIT.  The  Company  and  one of its  subsidiaries,
Interfilm  Technologies,  Inc.,  are the  plaintiffs  in a lawsuit  against Sony
Corporation  of  America  and  certain  of  its   affiliates  and   subsidiaries
(collectively,  "Sony") for breach of contract  and breach of duty of good faith
and fair dealing (the "IT  Litigation").  In November  1996,  Sony  asserted two
counterclaims  in the IT  Litigation.  The  complaint and  counterclaims  relate
solely to the business  activities  of the Company  prior to the Merger.  The IT
Litigation is under the control of and at the expense of an unaffiliated limited
liability partnership (the "Partnership"),  and is solely for the benefit of the
Company's pre-Merger stockholders as of June 21, 1996. Based upon the opinion of
the Company's counsel of record in the IT Litigation,  the Company believes that
the counterclaims are without merit.  However,  the Company may be liable in the
event that a judgment is rendered against the Company on the counterclaims,  and
the  assets  of  the   Partnership   may  not  be  sufficient  to  provide  full
indemnification.
See "Business."



                                USE OF PROCEEDS

      The Company  will not receive  any  proceeds  from the sale of the Offered
Shares.



                          MARKET FOR COMMON STOCK AND
                          RELATED STOCKHOLDER MATTERS

      The Common  Stock has been quoted on the Bulletin  Board since  October 1,
1995.  Currently,  the Common Stock trades under the symbol  "PLTN." Before July
22, 1996,  the Common  Stock  traded  under the symbol  "IFLM." The Common Stock
began trading publicly on the Nasdaq National  Market(R)  ("NMS") on October 28,
1993 under the symbol  "IFLM."  Before  October  28,  1993,  there was no public
market for the  Common  Stock.  On  September  30,  1995,  the Common  Stock was
delisted  from the NMS for  failure to  maintain  certain  net  tangible  assets
requirements.  The Company has  applied to have the Common  Stock  quoted on the
Nasdaq SmallCap  Market(sm).  There can be no assurance that the Company will be
able to meet the  listing  requirements  of the Nasdaq  SmallCap  Market,  or if
listed,  maintain  the  criteria for  continued  listing on the Nasdaq  SmallCap
Market.

      The following table gives the range of high and low bid information on the
Bulletin  Board for the Common  Stock for each  quarter  since the  Merger.  The
quotations reflect  inter-dealer  prices,  without retail mark-up,  mark-down or
commission, and may not represent actual transactions.

(1)   The prices in the table have been adjusted to give  retroactive  effect to
      the 1-for-10  reverse split of the  outstanding  Common Stock which became
      effective on July 19, 1996.  While the Merger was effective June 26, 1996,
      no RhoMed equity securities were exchanged for Common Stock until July 19,
      1996,  and  accordingly  prices  on and  prior  to July  19,  1996 may not
      accurately reflect the effect of the Merger.

      HOLDERS.  On August 11, 1997, the approximate  number of holders of record
of Common  Stock was 185 and the closing  sales price of the Common Stock on the
Bulletin Board was $1 3/4 per share.

      DIVIDEND POLICY. The Company has never declared or paid any cash dividends
on the Common Stock. The Company currently  intends to retain earnings,  if any,
for use in its business and therefore does not anticipate  paying cash dividends
in the foreseeable future.  Payment of future dividends,  if any, will be at the
discretion of the Board of Directors after taking into account various  factors,
including the Company's  financial  condition,  operating  results,  current and
anticipated  cash  needs and  plans  for  expansion.  The  Series A  Convertible
Preferred Stock has a dividend preference.
See "Description of Securities."

     TRANSFER  AGENT.  The transfer agent for the Common Stock is American Stock
Transfer & Trust Company.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

      The following  discussion and analysis should be read in conjunction  with
the Financial Statements and notes thereto filed as part of this Prospectus.

      Prior  to  May  10,  1995,  the  Company,   then  named  Interfilm,   Inc.
("Interfilm"),  had been  primarily  engaged in the business of  exploiting  the
rights related to its inactive motion pictures  ("Cinematic  Games"),  including
the production and  distribution  of Cinematic  Games for initial  exhibition in
theaters and  subsequently  in enhanced  versions for  distribution  to the home
market.  On May 10,  1995,  the  Board of  Directors  of  Interfilm  decided  to
substantially  curtail the  operations of Interfilm and its  subsidiaries.  As a
result of the Merger,  which became effective on June 25, 1996,  RhoMed became a
wholly-owned  subsidiary  of the Company,  with the holders of RhoMed  preferred
stock,  RhoMed  common stock and warrants and options to purchase  RhoMed common
stock  receiving  an aggregate  of an  approximately  96% interest in the equity
securities of the Company on

                                      20

a  fully-diluted  basis.  Since the former  stockholders of RhoMed retained more
than a 50%  controlling  interest  in the  Company,  the Merger was treated as a
reverse acquisition for accounting purposes. The historical financial statements
of the  Company  presented  prior to the  Merger  are  those of  RhoMed  and the
business of RhoMed represents the on-going business of the Company.

RESULTS OF OPERATIONS

      THREE AND NINE MONTH  PERIODS  ENDED MARCH 31, 1997  COMPARED TO THREE AND
NINE MONTH  PERIODS  ENDED MARCH 31,  1996.  During the three month period ended
March 31, 1997, the Company  discontinued  the  manufacture and sale of RhoChek,
the sole product sold by the Company,  due to insufficient  sales. There were no
revenues  from the sale of products in the three  month  period  ended March 31,
1997,  compared  to $12,240 in the three  month  period  ended  March 31,  1996.
Revenues in the nine month period ended March 31, 1997 were $22,184  compared to
$20,971 in the nine month period ended March 31, 1996.  The Company  received no
additional  revenues from the sale of products in the fiscal year ended June 30,
1997.

      In December 1996, the Company entered into an Option Agreement with Nihon,
pursuant to which the Company  received,  in January 1997, an initial payment of
$900,000 net of Japanese  withholding taxes of $100,000 (the "Initial Payment").
The Company has accounted for the Initial  Payment in the period ended March 31,
1997 by  recognizing  license fee revenue of $350,000 and  deferred  license fee
revenue of $550,000.  The deferred  license fee revenue will be  recognized if a
license  agreement is  consummated  with Nihon or  eliminated  if the Company is
required to repay certain monies to Nihon under the Option Agreement. There were
no revenues  from license fees or royalties in the three and nine month  periods
ended March 31, 1996.

      During the three month period  ended March 31, 1997,  the Company had four
Phase I grants under the Small Business  Innovative  Research  ("SBIR")  program
active with the National  Institutes  of Health of the  Department of Health and
Human  Services  ("NIH").  Grant  revenue  from these grants was $267,862 in the
three month period ended March 31, 1997,  compared to no revenues from grants in
the three month  period ended March 31,  1996.  Grant  revenue in the nine month
period ended March 31, 1997 was $267,862, compared to no revenues from grants in
the nine month  period  ended March 31,  1996.  The  Company  has  approximately
$100,000 in  additional  grant revenue which can be drawn under the four Phase I
grants.

      Research and  development  expenses  increased to $1,050,400 for the three
month period ended March 31, 1997 from $242,212 for the three month period ended
March 31,  1996,  with  expenses of  $2,300,669  for the nine month period ended
March 31, 1997  compared to $557,955  for the nine month  period ended March 31,
1996. The increase in expenses for both the current three and nine month periods
is  attributable  to  expansion  in the  scale  of the  Company's  research  and
development  operations,  which expanded following  completion of an offering of
RhoMed Common Stock in June 1996. The Company  substantially  increased research
and  development  spending,  primarily  relating to  development  of LeuTech for
diagnostic imaging of infections, including increased expenses for manufacturing
scale-up, consulting and clinical trials, and also relating to research expenses
on the Company's MIDAS technology.  The Company expects research and development
expenses  to continue  to  increase  in future  quarters as the Company  expands
manufacturing efforts and initiates clinical trials on LeuTech and significantly
expands its efforts to develop MIDAS

                                      21

technology  including the hiring of scientists and the  acquisition of equipment
and supplies in conjunction  with completion of the new research and development
facility in Edison, New Jersey.

      Pursuant to agreement  with Aberlyn  Holding Co., Inc. and its  affiliates
(collectively  "Aberlyn"),  effective April 30, 1997, the Company issued 255,641
shares  of Common  Stock,  valued  at the rate of 75% of the  average  per share
closing price for the twenty trading days immediately proceeding April 30, 1997,
in payment of  accrued  interest  from June 1, 1996  through  April 30,  1997 of
$303,171.  The  25%  discount  to  market  value  of  Common  Stock  represented
additional  interest  payable.  However,   management  believes  the  additional
interest will not have a material  adverse  effect on the financial  position or
operations of the Company.

      General and  administrative  expenses  increased to $793,370 for the three
month period ended March 31, 1997 from $405,111 for the three month period ended
March 31,  1996,  and  increased to  $1,740,125  for the nine month period ended
March 31, 1997 from  $1,017,061  for the nine month period ended March 31, 1996.
The increase is attributable  primarily to the hiring of certain key executives,
the  leasing  of  executive  offices in New  Jersey,  and  increased  travel and
consulting expenses.  General and administrative  expenses were also affected by
the  amortization  of the value of options and warrants  issued to  consultants.
General and  administrative  expenses  are expected to remain  approximately  at
current levels through the remainder of fiscal year 1997.

      Interest  income was  $36,330  and  $159,023  for the three and nine month
periods ended March 31, 1997, compared with no interest income for the three and
nine month  periods ended March 31, 1996.  The interest  income is primarily the
result of interest on net proceeds from a Common Stock offering of approximately
$8,400,000  completed in June 1996.  Interest  income is expected to increase in
coming  quarters as a result of increased cash balances from the proceeds of the
offering of the Company's  Series A Convertible  Preferred  Stock (the "Series A
Offering").

      Interest  expenses  decreased  to $84,927 for the three month period ended
March 31, 1997 compared with $143,465 for the three month period ended March 31,
1996,  and  decreased to $301,200 from $348,121 for the nine month periods ended
March 31,  1997 and 1996  respectively.  Interest  expense  for the nine  months
ending  March 31, 1997,  is  comprised  of (i)  interest on long-term  financing
provided by  Aberlyn,  the  principal  and  accrued  interest  of which  totaled
$1,905,477, (ii) interest on notes payable to stockholders, the principal amount
of which is $80,000, and (iii) interest on Senior Bridge Notes which were repaid
in full in the quarter ended September 30, 1996. As a result of repayment by the
Company  of  the  Senior  Bridge  Notes,  the  principal  amount  of  which  was
$1,000,000,  interest  expense is expected  to remain at current  levels for the
balance of the fiscal  year ended June 30,  1997,  and  substantially  below the
levels for the prior fiscal year.

      Net loss  increased to  $1,257,086  for the three month period ended March
31, 1997 compared with $914,009 for the three month period ended March 31, 1996,
and  increased  to  $3,525,506  for the nine month  period  ended March 31, 1997
compared to $2,161,427  for the nine month period ended March 31, 1996.  The net
loss per share decreased in both the three and nine month period ended March 31,
1997 compared to the prior year, a result related to the substantial increase in
the weighted average shares outstanding.  There were 11,745,837 shares of Common
Stock  outstanding  in the three month period  ended March 31, 1997  compared to
1,294,792 shares outstanding in the three month period ended March 31, 1996, and
11,618,271 shares outstanding in the nine month

                                      22

<PAGE>



period ended March 31, 1997 compared to 1,290,451 shares outstanding in the nine
month  period ended March 31, 1996.  The increase in the shares  outstanding  is
primarily  the  result of  issuance  of  7,664,844  shares  of  Common  Stock in
connection with the sale of Common Stock completed in June 1996.

      TEN MONTH  PERIOD  ENDED JUNE 30, 1996  COMPARED TO TEN MONTH PERIOD ENDED
JUNE 30,  1995.  License fees and  royalties  were zero for the ten months ended
June 30, 1996,  compared to $64,296 for the prior ten month period. The decrease
in license fees and  royalties is primarily  attributable  to the timing of when
these fees are earned;  during the ten months ended June 30, 1996, there were no
royalties on product sales or new license agreements. Sales of RhoChek, the sole
product sold by the Company, decreased $6,090 to $24,457 in the ten months ended
June 30, 1996, from $30,546 in the prior ten month period.

      Research and  development  expenses  increased by $391,983 to $869,896 for
the ten months ended June 30, 1996,  from  $477,913 in the ten months ended June
30, 1995.  The majority of the increase is  attributable  to LeuTech,  including
increased consulting, clinical trial and manufacturing scale-up expenses.

      General and  administrative  expenses  increased to  $1,250,343 in the ten
months  ended June 30,  1996,  from  $598,560  for the ten months ended June 30,
1995.  The  majority  of the  increase is due to the hiring of a Chairman of the
Board and Chief Executive Officer; Vice President of Finance and Chief Financial
Officer;  the leasing of general and  administrative  offices in New Jersey; and
increased travel and consulting expenses.

      Other  expenses  increased to $1,802,097 for the ten months ended June 30,
1996 from  $305,615  for the ten months  ended June 30,  1995.  The  increase is
attributable  primarily to increased interest expense,  commission and fees paid
in  connection  with the Company's  debt  offerings  ($168,970),  costs and fees
associated with the Merger  ($525,000),  costs and expenses  associated with the
relocation  of the  Company's  research and general and  administrative  offices
($284,000),  including primarily severance costs,  facility closing expenses and
recruiting  fees,  and the write down of certain  patents not currently  used in
development projects ($259,334).

      Net loss  increased to  $3,897,879  in the ten months ended June 30, 1996,
compared to $1,287,246 in the prior ten month period.

      FISCAL YEAR ENDED AUGUST 31, 1995 COMPARED TO FISCAL YEAR ENDED AUGUST 31,
1994.  Total revenues  decreased by $49,946 to $97,902 for the fiscal year ended
August 31,  1995,  from  $147,848 in the previous  fiscal year.  The decrease is
attributable to no grant revenue during fiscal year 1995 compared to $50,289 for
the previous fiscal year.

      Research and development  expenses were $619,354 for the fiscal year ended
August 31, 1995 compared to $584,941 for the previous fiscal year.

      General and  administrative  expenses decreased to $776,291 for the fiscal
year ended  August 31, 1995 from  $939,155 in the  previous  fiscal  year.  Such
decrease was primarily attributable to decreased offering expenses.

                                      23

<PAGE>



      Other expenses  increased to $341,121 for the fiscal year ended August 31,
1995 from $168,707 in the previous  fiscal year. The increase is attributable to
higher  interest  expense  due to a  higher  average  debt  balance  outstanding
throughout the 1995 fiscal year.

      Net loss for the fiscal year ended August 31, 1995 increased to $1,638,864
from $1,544,955 in the previous fiscal year.

LIQUIDITY AND CAPITAL RESOURCES

      Since its inception, the Company has incurred net operating losses and, as
of March 31, 1997, had an accumulated  deficit of  $11,658,444.  The Company has
financed its net operating losses through March 31, 1997 by a series of debt and
equity financings.

      At  March  31,  1997,  the  Company  had  cash  and  cash  equivalents  of
$4,863,237.  The  cash  is cash  equivalents  which  are  composed  of:  (i) the
remaining net proceeds from the Company's offering of Common Stock in June 1996,
(ii) the receipt from Nihon of $900,000 pursuant to the Agreement, and (iii) the
net proceeds from the Company's  Series A Offering of $2,680,591 as of March 31,
1997.

      For the nine  months  ended  March  31,  1997,  the net  decrease  in cash
amounted to $1,928,063.  Cash used for operating activities was $3,358,021,  net
cash used for investing activities was $128,293,  and cash provided by financing
activities  was  $1,558,251,  primarily  from the  proceeds  from  the  Series A
Offering less repayment of the Senior Bridge Notes.

      On December  2, 1996,  the  Company  commenced  the Series A Offering at a
price of $100,000 per unit,  with each unit consisting of 1,000 shares of Series
A Convertible  Preferred Stock. As of March 31, 1997, the Company had sold 30.63
units,  representing 30,630 shares of Series A Convertible  Preferred Stock, for
net proceeds to the Company of $2,680,591,  after deducting commission and other
expenses  of the Series A Offering.  The final  closing on the Series A Offering
was effective as of May 9, 1997, with the Company having sold an aggregate total
of 137.78 units,  representing 137,780 shares of Series A Convertible  Preferred
Stock,  for net  proceeds to the  Company of  approximately  $11,800,000,  after
deducting commission and other expenses of the Series A Offering.

      Pursuant to the Option Agreement, Nihon can maintain its option to license
certain  products  based on the MIDAS  technology  provided  Nihon makes certain
milestone payments based on progress in product development.  Nihon may exercise
its right to  negotiate a license  agreement at any time upon notice and payment
of additional monies to the Company.  In the event that the parties cannot agree
on terms of a license  agreement,  then the Company will be required to repay up
to $550,000 to Nihon.  There can be no assurance that the Company and Nihon will
ever  enter  into a  definitive  license  agreement,  that  additional  payments
provided  for in the  Option  Agreement  will be  made,  or that  the  strategic
alliance  between  the  Company  and Nihon  will  result in the  development  or
commercialization of any product.

      Pursuant  to the terms of the notes  payable  to  stockholders  ("Notes"),
repayment of principal and interest is required 75 days after the  completion of
a fiscal year when the Company has net assets of at least $5,000,000.

                                      24

      In March 1997,  the Company  entered into a ten-year lease on research and
development  facilities in Edison,  New Jersey,  with the lease term  commencing
August 1, 1997.  Minimum  future  lease  payments  escalate  from  approximately
$116,000  per year to $200,000  per year after the fifth year of the lease term.
The lease will expire in fiscal year 2007. The Company anticipates that the cost
of tenant improvements,  net of the landlord's contribution,  and acquisition of
laboratory equipment may exceed $1,500,000.

      Effective  August 1, 1997, the Company  entered into a five-year  lease on
administrative  offices in Princeton,  New Jersey. Minimum future lease payments
are approximately $97,000 per year.

      Commencing May 1997, the Company's monthly payments on long-term financing
provided  by  Aberlyn  increased  to  $91,695,  representing  payment of current
interest and  principal.  The final  monthly  payment is scheduled to be made in
April 1999.

      Under  certain  license  agreements  relating to  LeuTech,  the Company is
obligated  to make  minimum  payments of $100,000  per year in the fiscal  years
ending June 30, 1998 and 1999,  and  $125,000 in the fiscal year ending June 30,
2000.

      The Company's future capital requirements depend on numerous factors which
cannot  be  quantified,   including  continued  progress  in  its  research  and
development activities,  progress with pre-clinical studies and clinical trials,
prosecuting and enforcing patent claims,  technological and market developments,
the ability of the Company to establish product  development  arrangements,  the
cost of manufacturing scale-up, effective marketing activities and arrangements,
and licensing or acquisition activity.

      The Company has been seeking and expects to continue to seek to license or
acquire  certain  products and  technologies.  If the Company is  successful  in
acquiring a product or  technology,  substantial  funds may be required for such
acquisition  and  subsequent  development  or  commercialization.  To date,  the
Company has not completed an acquisition  and there can be no assurance that any
acquisition will be consummated in the future.

      The Company  believes  that the net proceeds from the Series A Offering of
$11,800,000 as of May 9, 1997 and the Initial Payment  received under the Option
Agreement,  together  with its other cash,  is  sufficient to fund the Company's
projected debt  obligations  and fund projected  operations  through fiscal year
1998.

      The Company anticipates incurring additional losses over at least the next
several years,  and such losses are expected to increase as the Company  expands
its research and development activities relating to its MIDAS technology and its
direct radiolabeling technology. To achieve profitability, the Company, alone or
with others,  must successfully  develop its technologies and proposed products,
conduct  pre-clinical  studies and clinical trials,  obtain required  regulatory
approvals and successfully manufacture and market such technologies and proposed
products.  The time required to reach  profitability  is highly  uncertain,  and
there can be no assurance that the Company will be able to achieve profitability
on a sustained basis, if at all.

                                   BUSINESS

GENERAL

      The   Company   and   its   wholly-owned   subsidiary,    RhoMed,   is   a
development-stage   biopharma  ceutical  company  dedicated  to  developing  and
commercializing products and technologies for diagnostic imaging, cancer therapy
and  ethical  drug  development  utilizing  peptide,   monoclonal  antibody  and
radiopharmaceutical technologies. The Company concentrates its activities in two
technology  areas,  each of which the  Company  believes  may be used to develop
products  with  potential   diagnostic  and  therapeutic   applications.   These
technologies  involve the Company's (i) patent-pending MIDAS technology and (ii)
patented and patent-pending direct radiolabeling technology.

      The  Company  believes  that the MIDAS  technology  represents  a platform
technology which may enable the design and synthesis of novel peptide analogs or
mimics.  Further, the Company believes that its MIDAS technology may provide the
Company with the flexibility to generate its own  pharmaceutical  products,  and
the  ability  to  target  and  complement   existing   product   portfolios  and
technological  bases of other  companies.  The Company  intends to seek to enter
into  collaborative  arrangements  to assist in development,  manufacturing  and
marketing of certain  proposed  products  utilizing  the MIDAS  technology.  The
Company has  entered  into a license  option  agreement  as to certain  proposed
products based on MIDAS technology. See "MIDAS Technology."

      The Company is developing two proposed  products  incorporating its direct
radiolabeling  technology,  (i) LeuTech,  an infection and inflammation  imaging
product,  and (ii) PT-5,  a  radiotherapeutic  peptide  somatostatin  analog for
cancer therapy. The Company is devoting substantial efforts and resources to the
development  of LeuTech,  which the Company  believes will be its first proposed
product to enter  Company-sponsored  clinical  trials.  The Company  anticipates
seeking one or more  marketing  partners for LeuTech prior to product  approval.
See "Direct Radiolabeling Technology."

      The Company is at an early stage of development  and has not yet completed
the  development  of any products  based on either its MIDAS  technology  or its
direct  radiolabeling  technology.  Accordingly,  the  Company  has not begun to
market or generate revenues from the  commercialization of any such products. It
will  be a  number  of  years,  if  ever,  before  the  Company  will  recognize
significant revenues from product sales or royalties. The Company's technologies
and products  under  development  will require  significant  time-consuming  and
costly research, development,  preclinical studies, clinical testing, regulatory
approval and significant additional investment prior to their commercialization,
which may never occur. There can be no assurance that the Company's research and
development  programs  will be  successful,  that its products  will exhibit the
expected  biological results in humans,  that its products will prove to be safe
and  efficacious,   that  its  products  will  obtain  the  required  regulatory
approvals,   demonstrate  substantial  therapeutic  or  diagnostic  benefit,  be
commercialized  on  a  timely  basis,  experience  no  design  or  manufacturing
problems,  be manufactured on a large scale, or be economical to market, or that
the  Company  or its  collaborators  will  be  successful  in  obtaining  market
acceptance of any of the Company's  products or generate  sufficient  revenue to
support  research and development  programs.  There can be no assurance that the
Company will be successful in entering into strategic alliances or collaborative
arrangements on

                                      26

<PAGE>



commercially  reasonable  terms,  if at  all,  that  such  arrangements  will be
successful,   or  that  the  parties  with  which  the  Company  will  establish
arrangements will perform their obligations under such arrangements. The Company
or its collaborators may encounter  problems and delays relating to research and
development,  regulatory approval,  manufacturing and marketing.  The failure by
the  Company to  successfully  address  such  problems  and delays  would have a
material adverse effect on the Company.  In addition,  no assurance can be given
that  proprietary  rights of third  parties  will not  preclude the Company from
marketing its proposed  products or that third parties will not market  superior
or equivalent products.

HISTORY AND MERGER

      The  Company was  incorporated  under the laws of the State of Delaware on
November  21,  1986.  From  November  4,  1993,  when the  Company,  then  named
Interfilm,  acquired  Interfilm  Technologies,  Inc.,  a New  York  corporation,
through  May 9,  1995,  Interfilm  was  primarily  engaged  in the  business  of
exploiting  the  rights  related  to its  interactive  motion  picture  process,
including the production and  distribution  of interactive  motion  pictures for
initial  exhibition  in  theaters  and  subsequently  in enhanced  versions  for
distribution  to the  home  market.  Interfilm  consummated  an  initial  public
offering on October 28,  1993,  and on May 10,  1995,  the Board of Directors of
Interfilm  decided to substantially  curtail the operations of Interfilm and its
subsidiaries. Interfilm conducted no business activities from May 10, 1995 until
June 25, 1996.

      MERGER  WITH  RHOMED.  On June  25,  1996,  a newly  formed,  wholly-owned
subsidiary of Interfilm,  Interfilm  Acquisition  Corporation  ("InSub"),  a New
Mexico corporation,  merged with and into RhoMed, a New Mexico corporation,  and
all of RhoMed's  outstanding  equity  securities were  ultimately  exchanged for
equity  securities  of the Company  (the  "Merger").  As a result of the Merger,
RhoMed  became a  wholly-owned  subsidiary  of the Company,  with the holders of
RhoMed preferred stock and RhoMed common stock (including the holders of "RhoMed
Derivative  Securities"  as  hereafter  defined)  receiving  an  aggregate of an
approximately  96%  interest  in  the  equity  securities  of the  Company  on a
fully-diluted basis.  Additionally,  all warrants and options to purchase common
stock of  RhoMed  outstanding  immediately  prior  to the  Merger  (the  "RhoMed
Derivative  Securities"),  including without  limitation,  any rights underlying
RhoMed's  qualified  and  nonqualified  stock option plans,  were  automatically
converted  into rights to receive,  upon  exercise,  Common  Stock,  in the same
manner in which shares of RhoMed common stock were  converted.  Since the former
stockholders  of  RhoMed  acquired,  by reason  of the  Merger,  more than a 50%
controlling interest in the Company, the Merger has been treated, for accounting
purposes,  as a reverse  acquisition.  Consequently,  the  historical  financial
statements of the Company prior to June 25, 1996, are those of RhoMed.

      In connection with the Merger,  certain  pre-Merger assets and liabilities
of the Company and one of its wholly-owned subsidiaries,  consisting principally
of certain intellectual property and the IT Litigation claims against Sony, were
transferred  to the  Partnership  for the  benefit of the  Company's  pre-Merger
stockholders as of a record date of June 21, 1996. See "Legal Proceedings."

      On July 19, 1996,  the Company  filed an amendment to its  Certificate  of
Incorporation (the "Charter  Amendment"),  which (i) effected the change of name
of the  Company  from  Interfilm,  Inc.  to  Palatin  Technologies,  Inc.,  (ii)
increased the total number of authorized shares of the Company's

                                      27

Common Stock from 10,000,000 to 25,000,000 and (iii) effected a 1-for-10 reverse
split of the Common Stock.

      As a result of the Merger and the Charter Amendment,  each share of RhoMed
preferred stock was converted into .46695404349 shares of Common Stock, and each
share of RhoMed  common stock was  converted  into  .184332593  shares of Common
Stock.

MIDAS TECHNOLOGY

      ROLE AND FUNCTION OF PEPTIDES. Peptides, short chains of amino acids, play
important  roles in  regulating  a  variety  of  biological  functions.  Natural
peptides  function by  conforming  or bending to fit specific  molecules on cell
surfaces, called receptors,  thereby signaling the cell to initiate a biological
activity.  Some important  biological functions that are affected in this manner
include overall growth and behavior,  inflammatory  responses,  immune responses
and wound healing.

      In order to effectively  regulate cell  signaling,  a peptide must bind to
its target receptor with high affinity. The affinity of a peptide for its target
receptor is highly  dependent on its  three-dimensional  shape or  conformation.
Many  naturally  occurring  peptides  are  flexible  and can  take  on  multiple
conformations,  allowing  them to  interact  with  more  than  one  type of cell
receptor,  and to control multiple functions within the body. However, when such
peptides are used as drugs, this multiple reactivity is a disadvantage as it may
lead to side effects. The ability to construct high-affinity,  receptor-specific
peptides  offers a significant  opportunity to develop potent  receptor-specific
drugs.

      INTRODUCTION  TO  MIDAS   TECHNOLOGY.   The  Company   believes  that  its
patent-pending  MIDAS  technology  can be used to rationally  design and produce
receptor-specific drugs. Using MIDAS, highly stable metallopeptide complexes are
formed,  in which the metal ion locks or constrains  the peptide into a specific
conformation. By designing MIDAS peptides to mimic the conformation required for
a specific receptor,  a stable,  receptor-specific  drug, with high affinity and
enhanced biological activity, can be made.  Radiopharmaceutical  products, which
may be diagnostic or therapeutic,  may be developed using radioactive metal ions
in MIDAS peptides.  Non-radioactive metal ions may be used in the development of
biopharmaceutical MIDAS peptides.

      The Company is engaged in research and  development on a number of product
opportunities  for its MIDAS technology,  including use as a thrombosis  imaging
agent, an infection imaging agent and an  immunostimulatory  agent, and believes
that  MIDAS  technology  may have  medical  applications  in a variety of areas,
including immune disorders,  cancers and cardiology.  No prediction can be made,
however,  as to when or  whether  the  areas in which  there are  ongoing  MIDAS
technology research projects will yield scientific discoveries,  or whether such
research projects will lead to commercial products

      RESEARCH PROJECTS. Certain pre-clinical work on development of MIDAS-based
products  has been  supported,  in part,  by three Phase I grants for  $100,000,
$93,948 and $94,970  under the SBIR  program  awarded to the Company by the NIH.
The Company  intends to apply for Phase II SBIR grants,  each in an amount of up
to $750,000,  although there can be no assurance that any Phase II grant will be
awarded.

                                      28

      OTHER  POTENTIAL  OPPORTUNITIES.  The  Company is  evaluating  a number of
product  opportunities  for  its  MIDAS  technology,   and  believes  that  this
technology may have medical applications in a variety of areas, including immune
disorders,  cancers and  cardiology.  The Company intends to expand research and
development  of  MIDAS  technology   applications  primarily  through  strategic
alliances  with  other  entities.  No  assurances  can  be  made  regarding  the
establishment or the timing of such alliances, and the failure to establish such
alliances on a timely basis could limit the  Company's  ability to develop MIDAS
technology and could have a material adverse effect on the Company.  The Company
expects  to  devote  resources  to  expand  research  and  development  of MIDAS
technology to the extent funding is available.

      OPTION AGREEMENT WITH NIHON. The Company entered into the Option Agreement
with Nihon, a Japanese developer and manufacturer of radiopharmaceutical  drugs.
Pursuant to the Option Agreement (i) Nihon has an option to exclusively  license
certain jointly developed  radiopharmaceutical  diagnostic products based on the
Company's  MIDAS  technology  and (ii) Nihon can  maintain  its option by making
certain milestone  payments based on progress in product  development.Nihon  may
exercise its right to negotiate a license  agreement at any time upon notice and
payment of  additional  monies to the Company.  There can be no  assurance  that
future  payments  provided for in the Option  Agreement  will be made,  that the
Company and Nihon will ever enter into a definitive license agreement, or that a
definitive  strategic  alliance between the Company and Nihon will result in the
development or  commercialization  of any product. In the event that Nihon gives
notice of its right to  negotiate a license  agreement,  and the parties  cannot
agree on terms of such license agreement,  the Company will be required to repay
certain monies to Nihon.  Failure to enter into a definitive  license agreement,
or being required to repay certain monies to Nihon,  may have a material adverse
effect on the  Company.  See  "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

DIRECT RADIOLABELING TECHNOLOGY

      The Company has developed and patented radiolabeling  technologies for the
direct radiolabeling of antibodies,  peptides and other proteins with diagnostic
and therapeutic radioisotopes.

      LEUTECH  DIAGNOSTIC  IMAGING  PRODUCT.  LeuTech,  a proposed product under
development  that  utilizes  direct  radiolabeling  technology,  is a murine (or
mouse)  monoclonal  antibody-based  product  designed  to be  labeled  with  the
diagnostic  radioisotope  technetium-99m.   When  labeled  with  technetium-99m,
LeuTech is intended to be used for diagnosis of  infections,  occult  abscesses,
sites of inflammatory disease and other conditions involving high concentrations
of white blood cells.

      The Company believes that LeuTech can be used for the rapid diagnosis of a
variety  of  difficult  to  diagnose  infections  and occult  abscesses.  Occult
abscesses are hidden infections that are generally characterized as being highly
localized.  Examples  of typical  occult  abscesses  include  infections  of the
intra-abdominal  area,  such as  intestinal,  spleen,  liver  or  urinary  tract
abscesses,  as well as  bone,  prosthetic  and  other  abscesses.  In a  typical
abscess, as in most infections, large numbers of white blood cells congregate at
the site of the  infection.  Thus,  if the location of  concentrations  of white
blood cells is known,  the site of the infection is also known. It is crucial in
the  diagnosis  and  treatment  of occult  abscesses  that the  location  of the
infection be  determined,  as location  will  frequently  determine  the type of
therapy which is appropriate.

                                      29

<PAGE>



      The most  specific  procedure  currently  available  for nuclear  medicine
imaging  of sites of  infection  involves  removal  of blood  from the  patient,
isolating white blood cells from the patient's  blood,  radiolabeling  the white
blood  cells and  injecting  the  radiolabeled  white  blood cells back into the
patient.  The  radiolabeled  white blood cells then  localize at the site of the
infection, and can be detected using nuclear medicine diagnostic equipment. This
procedure is expensive,  involves risks to patients and  technicians  associated
with blood handling, is difficult to perform and generally takes at least twelve
hours.

      LeuTech  has  been  formulated  as a  lyophilized,  or  freeze-dried,  kit
containing  the modified  antibody and reagents  required for the  radiolabeling
process.  Prior  to  use,  LeuTech  will be  labeled  with  technetium-99m  by a
radiopharmacy  or  by a  hospital's  nuclear  medicine  department.  LeuTech  is
designed to bind, in the body, to white blood cells already  present at the site
of the infection or circulating in the blood stream. Therefore, LeuTech does not
require handling or processing of patient blood.

      Preliminary  clinical  trials have been conducted under an IND application
held in the name of an investigator, using purified antibody or kits provided by
the Company.  Forty patient  studies have been completed at UCLA/Harbor  Medical
Center in Los Angeles, with images obtained in a variety of diseases,  including
acute and  suspected  appendicitis,  pulmonary  infections  and other  abdominal
infections.  In seven cases satisfactory images were not obtained, due primarily
to labeling or product formulation failures with early kit formulations. In some
cases,   diagnostic   images  have  been   obtained   within  five   minutes  of
administration  of  LeuTech,  and in all cases in which a  definitive  diagnosis
could be made,  diagnostic  images  have been  obtained  within 90  minutes.  An
additional seventeen patient studies were completed in Germany at the University
of  Gottingen,  using  kits  manufactured  by a  third  party  to the  Company's
specifications,   with  images  obtained  in   osteomyelitis   and  soft  tissue
infections.

      The Company has  entered  into an  exclusive  license  agreement  with the
Wistar  Institute  to use the  antibody  and cell  line used for  LeuTech  for a
defined field of use. Failure to meet the performance criteria for any reason or
any other event of default under the license agreement leading to termination of
the license agreement with Wistar Institute would have a material adverse effect
on the  Company.  While the  Company  has  negotiated  a  long-term  contractual
arrangement for the manufacture of the purified antibody  necessary for LeuTech,
there can be no  assurance  that such  contractor  will be able to  successfully
manufacture  purified  antibody  for  LeuTech on a  sustained  basis,  that such
contractor  will  remain in the  contract  manufacturing  business  for the time
required by the  Company,  or that the  Company  will be able to enter into such
contractual   arrangements  as  to  other  steps  and  components   required  to
manufacture  LeuTech. To date, the Company has only manufactured LeuTech in lots
preparatory to initiating  clinical  trial use, and has not  determined  whether
commercial  quantities  of LeuTech in  conformity  with these  standards  can be
manufactured on a sustained basis at an acceptable  cost. Such  manufacture must
be done under GMP requirements prescribed by the FDA and other agencies.

      The  Company  intends to file an IND  application  on LeuTech to  initiate
clinical trials on one or more selected  indications in the second half of 1997,
and to complete Phase III clinical  trials and file  regulatory  applications to
market with the FDA in the second half of 1998.  There can be no assurance  that
the Company's LeuTech development program will be successful,  that the FDA will

                                      30

<PAGE>



permit the Company's planned clinical trials to proceed, that LeuTech will prove
to be safe and efficacious in clinical trials,  that LeuTech can be manufactured
in commercially required quantities on a sustained basis at an acceptable price,
that LeuTech will obtain the required  regulatory  approvals or that the Company
or its  collaborators  will be  successful  in obtaining  market  acceptance  of
LeuTech.  The Company or its  collaborators  may  encounter  problems and delays
relating to research and development,  regulatory  approval,  manufacturing  and
marketing of LeuTech.

      PT-5 CANCER THERAPEUTIC  PRODUCT.  PT-5 is a rhenium-labeled  somatostatin
peptide analog being developed by the Company which is intended to treat cancers
by  regional  delivery  of  tumor  cell-targeted  radiotherapy.  PT-5  binds  to
somatostatin receptors.  Somatostatin, a natural peptide hormone involved in the
regulation  of cell  growth and  differentiation,  is  over-expressed  on a wide
variety of  cancers.  PT-5 is  intended  to target  such  cancers  and deliver a
therapeutic  dose of rhenium- 188, a  radioisotope  which emits high energy beta
radiation, to the cancer.

      The Company has developed a reproducible, easy to use, and high efficiency
direct  radiolabeling  method for PT-5;  developed a  lyophilized  final product
formulation;  conducted  biodistribution studies of PT-5 in normal animals using
several   different  routes  of   administration,   including   intravenous  and
intra-cavity  administration;  conducted  biodistribution  studies  of  PT-5  in
tumor-bearing  animals;  and demonstrated  that PT-5 has a specific  therapeutic
effect in animal models of three  different  human tumors -- lung,  prostate and
breast cancers.

      The  Company  believes  PT-5 may have  applications  for local or regional
administration to any  compartmentalized  cancer which is  somatostatin-receptor
positive.  The cancer must be  compartmentalized  in order for local or regional
administration  to work and must express  somatostatin  receptors in  reasonably
high levels in order to obtain the  targeting  benefits of PT-5.  Expression  of
somatostatin receptors varies by type of cancer.  However, until clinical trials
are completed,  specific  clinical utility and  applications,  if any, cannot be
determined.

      The  Company is working  with  researchers  at the  University  of Bonn in
Germany to initiate clinical trials of patients with bronchial cancer metastatic
to the pleural cavity.  PT-5 will be administered by infusion  directly into the
pleural  cavity.  This trial is  primarily  designed  to obtain  safety and dose
response data, and secondarily to obtain  evidence of efficacy,  including tumor
stasis or regression and improvement in cancer-associated biological markers.

      PT-5 requires a source of  radioactive  rhenium,  preferably  rhenium-188.
This  isotope can be  produced  by a variety of  methods,  including a generator
system;  however,  clinical grade radioactive rhenium is not currently available
in the United States.  The Company is aware of an experimental  generator system
developed  in  the  United  States  by Oak  Ridge  National  Laboratory,  and an
additional  experimental  generator system available in Europe. The Company does
not intend to seek to commercialize  any source of radioactive  rhenium,  but is
aware of other companies seeking to commercialize radioactive rhenium. There can
be no assurance  that,  regardless of the status of product  development  by the
Company,  any acceptable  form of radioactive  rhenium will ever be commercially
available in the United States or other  countries at acceptable  prices,  if at
all, in which  event the  Company may never be able to develop or  commercialize
PT-5.

                                      31

<PAGE>



      The Company is discussing entering into a collaborative arrangement with a
third party to use a specific somatostatin analog for PT-5, and both parties are
waiting to evaluate the results of preliminary  clinical trials. There can be no
assurance that the Company will be able to conclude a collaborative  arrangement
on acceptable terms, if at all. If the Company cannot conclude such arrangement,
the Company will either abandon PT-5 development or seek to develop a substitute
using MIDAS technology.  There can be no assurance that the Company will be able
to enter into an arrangement  with another party on acceptable  terms if at all,
or will be able to develop a substitute  using MIDAS  technology in a reasonable
period of time, or at all.  There can be no assurance  that the  Company's  PT-5
development  program  will be  successful,  that PT-5 will  exhibit the expected
biological results in humans, that PT-5 will prove to be safe and efficacious in
clinical trials, that the Company will obtain the required regulatory  approvals
for  PT-5,  or that the  Company  or its  collaborators  will be  successful  in
obtaining  market  acceptance  of PT-5.  The  Company or its  collaborators  may
encounter  problems and delays relating to research and development,  regulatory
approval, manufacturing and marketing of PT-5.

RHOCHEK PRODUCT

      The Company had manufactured and marketed, under the trade name RhoChek, a
quality  control  test  product for  measuring  the  immunoreactive  fraction of
radiolabeled antibodies specific to certain cancer antigens. Due to insufficient
sales,  the  Company  discontinued  product  sales of RhoChek in the fiscal year
ended June 30, 1997.

MARKETS FOR PRODUCTS

      The  Company's  proposed  products  and  technologies  are  intended to be
utilized in two  distinct  pharmaceutical  markets.  One market,  intended to be
addressed by LeuTech,  PT-5 and certain  proposed  products  resulting  from the
Company's MIDAS technology, is the radiopharmaceutical market. The other market,
intended  to be  addressed  by other  proposed  products  resulting  from  MIDAS
technology, is the larger biopharmaceutical market.

      The  radiopharmaceutical  market  involves  both  diagnostic  imaging  and
therapeutic applications.  For imaging, trace amounts of a radioisotope bound to
a radiopharmaceutical drug are injected into a patient and detected with nuclear
medicine   diagnostic   equipment,   generally  a  gamma  camera.  For  therapy,
radioisotopes which emit radiation lethal to cancer cells are employed.

      The Company  believes  that  proposed  products  resulting  from its MIDAS
technology  can be used for a variety of  biopharmaceutical  applications  where
non-radioactive but  receptor-specific  drugs are desired.  The Company believes
the MIDAS technology may be applicable to a number of disease states,  including
immune  disorders,  cancer,  and cardiac therapy.  There are a limited number of
receptor-specific,  peptide-based drugs commercially  available,  but none which
employ a  metallopeptide.  There can be no assurance that MIDAS  technology will
result in the development of any such drugs.

RESEARCH AND DEVELOPMENT EXPENDITURES

      In the nine months  ended March 31,  1997,  the ten months  ended June 30,
1996 and the fiscal year ended August 31, 1995,  the Company  spent  $2,300,669,
$869,896 and $619,354, respectively, on research and development activities.

GRANTS AND COLLABORATIVE RESEARCH

      The Company  applies  for grants  with the NIH and other  federally-funded
agencies  ("Research  Grants") to develop its products and  technologies.  Since
inception,  the  Company has been  awarded  over $2.4  million in  peer-reviewed
Research  Grants.  During the fiscal year ended June 30,  1997,  the Company had
four active Phase I SBIR Research  Grants.  Generally,  the maximum  amount of a
Phase I SBIR Research  Grant is $100,000,  and the maximum  amount of a Phase II
SBIR Research  Grant is $750,000.  There can be no assurance that any additional
Research Grants will be awarded.

      The Company has, where scientifically or technologically merited, actively
solicited  Cooperative  Research  and  Development   Agreements  ("CRADA")  with
agencies  of  the  federal  government,   involving  collaborative   development
activities with the Company. The Company currently has no active CRADAs, but has
completed  CRADAs  with Los  Alamos  National  Laboratory,  Brookhaven  National
Laboratory,  Oak Ridge  National  Laboratory  and  Sandia  National  Laboratory,
relating primarily to radiopharmaceutical drug development,  including PT-5, and
animal studies of proposed radiopharmaceutical products.

COMPETITION

      The  biopharmaceutical  and  radiopharmaceutical   industries  are  highly
competitive.  In the biopharmaceutical industry, there are a number of companies
developing  peptide-based  drugs,  including  companies  exploring  a number  of
different approaches to making  conformationally-constrained  short peptides for
use as therapeutic drugs. In the radiopharmaceutical industry, there are several
companies   devoted  to   development   and   commercialization   of  monoclonal
antibody-based  products and  peptide-based  products.  The Company is likely to
encounter  significant   competition  with  respect  to  its  proposed  products
currently under development. Many of the Company's competitors which are engaged
in  the   biopharmaceutical   field,   and  in  particular  the  development  of
peptide-based  products,  have substantially greater financial and technological
resources and marketing  capabilities than the Company,  and have  significantly
greater   experience  in  research  and  development.   Many  of  the  Company's
competitors  which  are  engaged  in  the  radiopharmaceutical   field,  and  in
particular the development of antibody- and peptide-based products, have greater
financial  and  technological  resources  and  marketing  capabilities  than the
Company, and have significantly  greater experience in research and development.
Accordingly,  the Company's  competitors may succeed in developing  products and
underlying  technologies  more  rapidly  than  the  Company,  and in  developing
products  that are more  effective  and useful and are less costly than any that
may be  developed  by the  Company,  and may  also be more  successful  than the
Company in  manufacturing  and marketing such products.  Academic  institutions,
hospitals,   governmental   agencies  and  other  public  and  private  research
organizations are also conducting research and seeking patent protection and may
develop competing products or technologies on their own or through collaborative
arrangements.

                                      33

<PAGE>



      The  Company  believes  that  the  technological  attributes  of  LeuTech,
including  the ease of  preparation,  rapidity  of imaging,  apparent  targeting
specificity and use of technetium-99m  (the most widely available  radioisotope)
will enable the Company to compete  effectively  in this  market.  However,  the
Company is aware of at least one company  developing an  antibody-based  product
which may  compete  with  LeuTech as to certain  indications,  which  product is
marketed in certain  European  countries  and for which  regulatory  approval is
pending  in the United  States.  The  Company  is also aware of another  company
developing  a  peptide-based  product  which may also compete with LeuTech as to
certain indications.

      The  Company  is aware of a number of  companies  developing  technologies
relating  to the use of  peptides  as drugs,  including  a variety of  different
approaches to making conformationally-constrained short peptides.

      The Company is pursuing areas of product development in which there is the
potential for extensive technological  innovation in relatively short periods of
time.  The Company's  competitors  may succeed in  developing  products that are
safer or more effective  than those of the Company's  proposed  products.  Rapid
technological  change or  developments  by others  may  result in the  Company's
proposed products becoming obsolete or non-competitive.

PATENTS AND PROPRIETARY INFORMATION

      The Company aggressively seeks patent protection for its technology in the
United  States  and,  selectively,  in  those  foreign  countries  where  in the
Company's  judgment  such  protection  is  important to the  development  of the
Company's business.

      The   Company's   patents  and  pending   applications   are  directed  to
radiolabeling of antibodies,  antibody fragments,  and peptides; MIDAS peptides;
and to methods for making and using the foregoing in diagnostic and  therapeutic
applications.  The Company owns or has rights to 16 U.S. patents,  eight pending
U.S.  patent  applications,  four  allowed  U.S.  patent  applications  and nine
counterpart   patents  and  eight  pending   applications  in  selected  foreign
countries.

      Certain of the patents and pending  applications owned by the Company have
been  assigned  to Aberlyn to secure  long-term  financing  but the  Company has
retained  the  exclusive  right to practice  these  patents  itself and to grant
licenses under these patents to third parties.  The Company is obligated to make
monthly  payments to Aberlyn in discharge of the  Company's  debt  obligation of
$91,695 per month through May 1, 1999. On completion of scheduled payments,  all
rights to the patents and pending  applications will be assigned to the Company.
In the event of default by the  Company,  Aberlyn  has the right to require  the
Company to cease  using the  patents,  and to sell or  exclusively  license  the
patents to other  parties.  The  patents  and  pending  applications  pertain to
LeuTech and PT-5. In addition,  the Company has semi-exclusive rights in a basic
United States patent  relating to direct  radiolabeling  of antibodies,  and its
Canadian counterpart.

      Two of the  Company's  basic  U.S.  patents  for direct  radiolabeling  of
antibodies and other proteins were involved in a  priority-of-invention  contest
(interference) in the U.S. Patent and Trademark Office with a patent application
owned by a third party.  This  proceeding  has been  settled,  and the Company's
patents  have  emerged  from  reissue  proceedings  in  which  the  scope of the
Company's  claims has been  somewhat  limited.  The  Company  believes  that the
current claim scope

                                      34

<PAGE>



will not materially  adversely affect the Company's current product  development
plans, and is sufficient to protect the Company's underlying inventions.

      One of the Company's  granted European  patents  (directed to selection of
patient-specific  antibody cocktails) is involved in an opposition proceeding at
the European Patent Office. The Company has received a favorable first decision,
but the opposing party has filed an appeal.  The Company believes that the final
outcome of this  proceeding,  even if adverse  to the  Company,  will not have a
material adverse effect on the Company's current product development plans.

      The Company's  success will depend in  substantial  part on its ability to
obtain  patents,  defend and enforce its  patents,  maintain  trade  secrets and
operate without  infringing upon the proprietary  rights of others,  both in the
United States and abroad.

      In general,  the patent positions of companies relying upon  biotechnology
are highly uncertain in general and involve complex legal and factual questions.
To date there has emerged no consistent  policy  regarding the breadth of claims
that are  properly  accorded  to  biotechnology  patents.  There  can thus be no
assurance  that  patents  will issue from the patent  applications  filed by the
Company or its  licensors or that the scope of any claims  granted in any patent
will provide meaningful proprietary protection or a competitive advantage to the
Company.  There can be no  assurance  that the  validity  or  enforceability  of
patents  issued or licensed to the Company will not be  challenged by others or,
if challenged, will be upheld by a court. In addition, there can be no assurance
that  competitors  will not be able to circumvent any patents issued or licensed
to the Company.  In the United  States,  patent  applications  are maintained in
secrecy until they issue as patents,  and thus  publications  in the  scientific
literature lag behind actual discoveries. Scientific publications also generally
appear  after a patent  application,  if any,  is filed.  As a result of delayed
publication, the Company cannot be certain that its scientists were the first to
make inventions covered by its patents and patent applications.

      In the event a third party has also filed a patent application relating to
an  invention  claimed  in a Company  patent  application,  the  Company  may be
required to participate in an interference  proceeding adjudicated by the United
States  Patent and  Trademark  Office to determine  priority of  invention.  The
possibility  of  an   interference   proceeding   could  result  in  substantial
uncertainties  and  cost  for the  Company,  even  if the  eventual  outcome  is
favorable to the Company.  An adverse outcome could result in the Company losing
patent  protection for the subject of the  interference,  subject the Company to
significant  liabilities  to third  parties  and  require  the Company to obtain
licenses  from  third  parties  at  undetermined  cost  or to  cease  using  the
technology.

      While no patent that would be infringed by manufacture, use or sale of the
Company's  proposed  products  has come to the  attention  of the  Company,  the
Company's  proposed  products are still in the  development  stage,  and neither
their  formulations  nor their method of  manufacture  is  finalized.  Moreover,
patents,  the claims of which would be  infringed  by the  Company's  commercial
activities,  might not have yet been issued. There can thus be no assurance that
the  manufacture,  use or sale  of the  Company's  proposed  products  will  not
infringe  patent  rights  of  others.   The  Company  may  be  unable  to  avoid
infringement  of any such  patents  and may have to seek a  license,  defend  an
infringement  action, or challenge the validity of such patents in court.  There
can be no assurance that a license will be available to the Company,  if at all,
upon terms and  conditions  acceptable  to the Company or that the Company  will
prevail in any patent litigation. Patent litigation is costly and time

                                      35

<PAGE>



consuming,  and there can be no assurance that the Company will have  sufficient
resources  to pursue such  litigation.  If the Company does not obtain a license
under any such patents, is found liable for infringement, or is not able to have
them declared invalid,  the Company may be liable for significant money damages,
may  encounter  significant  delays in bringing  products  to market,  or may be
precluded  from  participating  in the  manufacture,  use or sale of products or
methods of treatment covered by such patents.

      The Company relies substantially in its product development  activities on
certain  technologies  which are  neither  patentable  nor  proprietary  and are
therefore potentially available to the Company's  competitors.  The Company also
relies on certain  proprietary  technologies  (trade secrets and know-how) which
are not  patentable.  Although  the  Company  has  taken  steps to  protect  its
unpatented   trade   secrets  and   know-how,   in  part   through  the  use  of
confidentiality  agreements  with its employees,  consultants and certain of its
contractors,  there  can be no  assurance  that  these  agreements  will  not be
breached,  that the Company would have adequate  remedies for any breach or that
the Company's trade secrets will not otherwise  become known or be independently
developed or discovered by competitors.  If the Company's employees,  scientific
consultants or collaborators develop inventions or processes  independently that
may be applicable to the Company's product candidates,  disputes may arise about
ownership  of  proprietary  rights  to  those  inventions  and  processes.  Such
inventions and processes will not necessarily become the Company's property, but
may remain the  property of those  persons or their  employers.  Protracted  and
costly  litigation  could be necessary to enforce and determine the scope of the
Company's  proprietary  rights.  Failure to obtain or maintain  patent and trade
secret protection,  for any reason,  could have a material adverse effect on the
Company.

      Certain of the  Company's  patents are  directed to  inventions  developed
within  the  Company or within  academic  institutions  from  which the  Company
earlier acquired rights to such patents with funds from United States government
agencies.  As a result of these  arrangements,  the United States government may
have rights in certain inventions developed during the course of the performance
of federally  funded  projects as required by law or agreements with the funding
agency.

      Several bills  affecting  patent rights have been introduced in the United
States  Congress.  These bills address various aspects of patent law,  including
publication of pending patent  applications,  modifications  of the patent term,
re-examination, subject matter and enforceability. It is not certain whether any
of  these  bills  will be  enacted  into law or what  form  new  laws may  take.
Accordingly,  the effect of  legislative  change on the  Company's  intellectual
property estate is uncertain.

GOVERNMENTAL REGULATION

      The manufacture and marketing of the Company's  proposed products requires
approval  of the FDA and  comparable  agencies  in foreign  countries  and state
regulatory authorities.  The FDA has established regulations and guidances which
apply,  among other  things,  to the clinical  testing,  manufacturing,  safety,
efficacy,  labeling, storage, record keeping, approval,  advertising,  promotion
and marketing of the Company's proposed products.  Noncompliance with applicable
requirements  can result in fines,  recalls or  seizures of  products,  total or
partial  suspension  of  production,  refusal  of the FDA to  approve  marketing
applications and criminal prosecution.

                                      36

<PAGE>



      In most cases, there is a substantial period of time between conception of
a proposed  product and its approval for commercial  sale.  Determining  product
formulation  and  manufacturing  can take a number of years to complete,  as can
pre-clinical studies. Clinical trials and related studies can also take a number
of  years  to  complete.  The  period  between  the  date  of  submission  of an
application  for  approval  to market  and the date of  approval  by the FDA has
averaged  two to four  years  for  diagnostic  imaging  products,  although  the
approval process may take longer.  The length of time of the approval process is
a function of a number of variables, including the quality of the submission and
studies  presented,  the potential  contribution  that the proposed product will
make in improving  the  treatment of the disease in question and the workload at
the FDA. There can be no assurance that any of the Company's  proposed  products
will  successfully  proceed  through  the  approval  process  or that any of the
proposed  products  will be approved in any specific  period of time.  Depending
upon marketing and distribution plans and arrangements for a particular product,
the Company may require  additional  time before a proposed  product can be made
available for commercial sale, if at all.

      The steps  required  before  pharmaceutical  products  can be produced and
marketed usually include  pre-clinical  non-human studies,  the filing of an IND
application,  clinical trials and the filing and approval of a Biologics License
Application  ("BLA")  for  products  classified  as  "biologics"  or filing  and
approval of a New Drug Application ("NDA") for drug products. LeuTech is subject
to the  requirement  of a BLA,  while PT-5 and  proposed  products  based on the
Company's MIDAS technology are subject to the requirement of a NDA.

      Pre-clinical  studies are conducted in the  laboratory and in animal model
systems  to gain  preliminary  information  on the drug's  effectiveness  and to
identify  major safety  problems.  The results of these studies are submitted to
the FDA as part of the IND  application  before approval can be obtained for the
commencement of testing in humans.  The clinical  testing program required for a
new biological or  pharmaceutical  product  typically  involves three sequential
phases, but the phases may overlap. In the initial clinical evaluation, Phase I,
the product is tested for safety, dosage tolerance, distribution,  excretion and
pharmacodynamics.  Phase II involves studies in a limited patient populations to
evaluate the effectiveness of the product for a particular indication, to refine
optimal dosage and schedules of  administration,  and to identify  possible side
effects and risks. For diagnostic imaging agents, such as LeuTech, typically the
smallest quantity of product producing satisfactory images will be employed. For
therapeutic  products  the side  effects  and risks of  increased  doses must be
balanced against increased  therapeutic benefits.  For radiolabeled  therapeutic
products, such as PT- 5, the radiation dose to critical organs provides an upper
limit to the dosage.  When a product appears to be effective in Phase II trials,
it is then evaluated in Phase III clinical  trials.  Phase III trials consist of
additional  testing for effectiveness and safety with an expanded patient group,
usually at  multiple  test sites.  Therapeutic  products  are often  compared to
standard   treatments,   if  such  treatments   exist,  to  determine   relative
effectiveness in randomized trials.

      When Phase III studies are complete,  the results of the  pre-clinical and
clinical studies, along with manufacturing information, are submitted to the FDA
in the form of either a BLA or a NDA. Both the BLA and NDA involve  considerable
data collection,  verification and analysis, the preparation of summaries of the
production and testing processes,  pre-clinical studies and clinical trials. The
FDA must  approve  the BLA or NDA,  as  applicable,  before the  product  may be
marketed.  The FDA may deny a BLA or NDA if applicable  regulatory  criteria are
not satisfied, may require

                                      37

<PAGE>



additional  testing  or  information,  or may  require  post-marketing  testing,
including extensive Phase IV studies, and surveillance to monitor the effects of
the product in general use.  Product  approvals  may be withdrawn if  compliance
with  regulatory  standards is not  maintained  or if problems  occur  following
initial  marketing.  In  addition,  the  FDA may in  some  circumstances  impose
restrictions on the use of the drug that may limit its market potential.

      In addition to obtaining  either BLA or NDA approval  from the FDA for any
of the Company's proposed  products,  if the proposed product is manufactured in
the United States the drug manufacturing  establishment must be registered with,
and inspected by, the FDA. Such drug manufacturing establishments are subject to
biennial  inspections by the FDA, and must comply with GMP regulations  enforced
by  the  FDA.  To  supply  products  for  use  in  the  United  States,  foreign
manufacturing  establishments  must  comply with GMP and are subject to periodic
inspection  by the FDA or by  corresponding  regulatory  agencies  in such other
countries under reciprocal  agreements with the FDA. In complying with standards
established  by the FDA,  manufacturing  establishments  must continue to expend
time,  money and effort in the areas of production and quality control to ensure
full technical  compliance.  Components of LeuTech are  manufactured by contract
manufacturing establishments both in the United States and in foreign countries,
and  the  Company  anticipates  that  PT-5  will  be  manufactured  by  contract
manufacturing  establishments.   The  Company  is  dependent  on  such  contract
manufacturing  establishments  for, and will have only limited control over, the
commercial  manufacturing  of it's proposed  products in compliance with FDA and
other regulatory requirements.

      The Company has very limited  experience  in conducting  clinical  trials.
Clinical  trials are  conducted  in  accordance  with FDA  regulations  covering
protection  of human  subjects and clinical  practice  protocols  detailing  the
objectives  of the study,  parameters  for  monitoring  safety and  criteria for
determining effectiveness. The Company will either need to rely on third parties
to design and administer  required  clinical trials or expend  resources to hire
additional  personnel  to  administer  such  clinical  trials.  There  can be no
assurance  that the Company will be able to find  appropriate  third  parties to
design  and  administer  clinical  trials  or that  the  Company  will  have the
resources to hire personnel to administer clinical trials.

      No proposed  product being evaluated by the Company has been submitted for
approval or approved by the FDA or any other regulatory authority for marketing,
and there can be no  assurance  that any such  product will ever be approved for
marketing or that the Company will be able to obtain the labeling claims desired
for its proposed products. The Company is and will continue to be dependent upon
laboratories and medical  institutions  conducting its pre-clinical  studies and
clinical  trials to maintain both good  laboratory  and good clinical  practices
consistent with FDA  regulations.  Data obtained from  pre-clinical  studies and
clinical trials are subject to varying  interpretations which could delay, limit
or prevent FDA  regulatory  approval.  Delays or rejections  may be  encountered
based  upon  changes  in FDA  policy  for drug  approval  during  the  period of
development and FDA regulatory review. Similar delays also may be encountered in
foreign countries.

      There can be no assurance  that FDA or other  regulatory  approval for any
proposed products developed by the Company will be granted on a timely basis, or
at all. Delay in obtaining or failure to obtain such  regulatory  approvals will
have a material adverse effect on the Company.

                                      38

MANUFACTURING AND MARKETING

      To  be  successful,   the  Company's  products  must  be  manufactured  in
commercial  quantities  under  GMP  requirements  prescribed  by the  FDA and at
acceptable  costs.  The  Company  has not yet  manufactured  any  pharmaceutical
products in commercial  quantities and currently does not have the facilities to
manufacture  any products in commercial  quantities  under GMP. In the event the
Company  determines  to  establish a  manufacturing  facility,  it will  require
substantial additional funds, the hiring and retention of significant additional
personnel  and  compliance  with  extensive  regulations  applicable  to  such a
facility.   The  Company  has  no  experience   in   commercial   pharmaceutical
manufacturing,  and there can be no  assurance  that the Company will be able to
establish such a facility successfully and, if established, that it will be able
to manufacture products in commercial quantities for sale at competitive prices.
If the  Company  determines  to rely on  collaborators,  licensees  or  contract
manufacturers for the commercial  manufacture of its products,  the Company will
be dependent on such  corporate  partners or other  entities  for, and will have
only limited control over, the commercial  manufacturing of its products.  While
the Company has entered into  manufacturing  arrangements as to certain portions
of the  manufacture  of LeuTech,  there can be no  assurance  that the  contract
manufacturer will perform as agreed or will remain in the contract manufacturing
business for the time required by the Company,  or that the Company will be able
to enter into such  manufacturing  arrangements as to remaining  portions of the
manufacture of LeuTech.  There can be no assurance that the Company will be able
to enter  into any such  manufacturing  arrangements  as to its  other  proposed
products on acceptable terms, if at all.

      LeuTech requires purified monoclonal antibody, made from a specific parent
cell  line.  There  are,  on a  global  basis,  a  limited  number  of  contract
manufacturers capable of producing purified monoclonal  antibodies.  The Company
has  entered  into  a  manufacturing  arrangement  with a  third-party  contract
manufacturer for production and purification of the monoclonal antibody required
for LeuTech,  and has retained other  third-party  manufacturers for compounding
steps, vialing and lyophilization.

      Proposed  products  resulting from MIDAS technology and PT-5 are synthetic
peptides.  The peptides are synthesized from readily  available amino acids, and
the  production  process  involves  well-established   technology.  The  Company
currently  contracts  with  third-party  manufacturers  for  the  production  of
peptides and anticipates doing so in the future.

      PT-5   requires   a  source  of   radioactive   rhenium  in  order  to  be
commercialized.  There can be no  assurance  that,  regardless  of the status of
product  development by the Company,  any acceptable form of radioactive rhenium
will ever be commercially available in the United States or other countries. See
"Direct Radiolabeling Technology -- PT-5 Cancer Therapeutic Product."

      The Company intends to package and ship its  radiopharmaceutical  products
in the form of  non-radioactive  kits.  Prior  to  patient  administration,  the
product would be radiolabeled  with the specified  radioisotope,  generally by a
specialized radiopharmacy. The Company does not intend to sell or distribute any
radioactive substance.

      The Company has limited  experience in marketing,  including  distribution
and sales, of  pharmaceutical  products,  and will have to develop a sales force
and/or rely on its collaborators,

                                      39

<PAGE>



licensees or arrangements with others to provide for the marketing, distribution
and sales of its products.  If the Company  determines to rely on collaborators,
licensees or arrangements with others for the marketing,  distribution and sales
of its proposed  products,  the Company will be dependent on such  collaborators
and others for, and will have only limited control over, marketing, distribution
and sales of its proposed products.

      Successful sales of the Company's  proposed  products in the United States
and other countries will depend on the  availability  of adequate  reimbursement
from   third-party   payors  such  as   governmental   entities,   managed  care
organizations and private insurance plans.  Reimbursement by a third-party payor
may depend on a number of factors,  including the payor's determination that use
of a product is safe and efficacious,  neither experimental nor investigational,
medically  necessary,  appropriate for the specific  patient and cost effective.
Since reimbursement  approval is required from each payor individually,  seeking
such  approvals  is a  time-consuming  and costly  process.  Third-party  payors
routinely  limit  reimbursement  coverage  and in many  instances  are  exerting
significant  pressure  on medical  suppliers  to lower  their  prices.  There is
significant uncertainty concerning third-party  reimbursement for the use of any
pharmaceutical  product incorporating new technology,  and there is no assurance
that  third-party  reimbursement  will be available for the  Company's  proposed
products, or that such reimbursement,  if obtained,  will be adequate. Less than
full  reimbursement  by  governmental  and  other  third-party  payors  for  the
Company's  products  would  adversely  affect  the  market  acceptance  of these
products and would also have a material adverse effect on the Company.  Further,
health care reimbursement systems vary from country to country, and there can be
no assurance  that  third-party  reimbursement  will be made  available  for the
Company's proposed products under any other reimbursement system.

PRODUCT LIABILITY AND INSURANCE

      The  Company's  business  may be affected by potential  product  liability
risks which are inherent in the testing, manufacturing and marketing of proposed
pharmaceutical  products  to be  developed  by  the  Company.  There  can  be no
assurance  that  product  liability  claims  will not be  asserted  against  the
Company, its collaborators or licensees.  The use of proposed products developed
by the  Company in  clinical  trials and the  subsequent  sale of such  proposed
products is likely to cause the Company to bear all or a portion of those risks.
Such litigation claims could have a material adverse effect on the Company.  The
Company  has  liability  insurance  providing  up  to  $1,000,000  coverage  per
occurrence  and in the aggregate as to certain  clinical  trial risks,  and will
seek   to   obtain   additional   product   liability   insurance   before   the
commercialization  of its  products.  There can be no assurance,  however,  that
insurance  will be available to the Company on acceptable  terms,  if at all, or
that such  coverage  once  obtained  would be  adequate  to protect  the Company
against  future  claims or that a medical  malpractice  or other claim would not
materially  and  adversely  affect  the  Company.  Furthermore,  there can be no
assurance  that any  collaborators  or  licensees  of the Company  will agree to
indemnify the Company, be sufficiently insured or have a net worth sufficient to
satisfy any such product liability  claims. In addition,  products such as those
proposed  to be sold by the  Company  may be subject  to recall  for  unforeseen
reasons. Such a recall could have a material adverse effect on the Company.

                                      40

EMPLOYEES

      As of June 30, 1997, the Company employed 16 persons full time, of whom 11
were  engaged in  research  and  development  activities  and 5 were  engaged in
administration and management. Of the Company's employees, 4 hold Ph.D. degrees.
The Company, from time to time, hires scientific  consultants to work on certain
of its research and development programs.  The Company believes that it has been
successful in attracting skilled and experienced scientific personnel;  however,
competition for such personnel is intense.

      None of the  Company's  employees  is covered by a  collective  bargaining
agreement. The Company's employees have executed confidentiality agreements. The
Company considers relations with its employees to be good.

       The Company relies, in substantial  part, and for the foreseeable  future
will rely, on certain  independent  organizations,  advisors and  consultants to
provide certain services,  including substantially all aspects of manufacturing,
regulatory approval and clinical management.  There can be no assurance that the
services of independent organizations, advisors and consultants will continue to
be available  to the Company on a timely basis when needed,  or that the Company
could find  qualified  replacements.  The  Company's  advisors  and  consultants
generally  sign  agreements  that provide for  confidentiality  of the Company's
proprietary  information.  However,  there can be no assurance  that the Company
will be able to maintain the  confidentiality of the Company's  technology,  the
dissemination of which could have a material adverse effect on the Company.

PROPERTY

      The Company's  headquarters are located at 214 Carnegie Center, Suite 100,
Princeton,  New Jersey,  where it leases approximately 4,000 square feet under a
lease which  expires July 31, 2002.  In March 1997,  the Company  entered into a
ten-year  lease on  approximately  10,500  square feet for use as a research and
development  facility in Edison, New Jersey, with a lease term commencing August
1,  1997.  The  Company  also  leases   approximately   14,000  square  feet  in
Albuquerque,  New Mexico,  which currently serves as the Company's  research and
development  facility,  under  a lease  which  expires  August  31,  1997.  Upon
expiration of the Albuquerque  facility lease,  the Company intends to close the
Albuquerque facility and relocate all its research and development to the Edison
facility.

LEGAL PROCEEDINGS

      In  April  1996,  prior  to  the  Merger,  the  Company  and  one  of  its
subsidiaries,   Interfilm  Technologies,  Inc.  (collectively,  "IT"),  filed  a
complaint  initiating the IT Litigation in the Supreme Court of the State of New
York, County of New York, against Sony for breach of contract and breach of duty
of good  faith  and fair  dealing,  seeking  contract  damages  of $18  million,
punitive damages of $100 million and costs. The IT Litigation  relates solely to
the business  activities of the Company prior to the Merger and, pursuant to the
Merger,   was  included  in  certain  assets  and  liabilities  of  the  Company
transferred  to  the  Partnership  solely  for  the  benefit  of  the  Company's
stockholders  as of June 21,  1996.  Accordingly,  the  litigation  is under the
control of and at the expense of the  Partnership,  and the Company will receive
no financial benefit from the litigation, even if the litigation is successfully
concluded. The assets of the Partnership, including any proceeds from

                                      41

<PAGE>



the IT Litigation,  whether by judgment,  settlement or otherwise, are available
to indemnify the Company from certain liabilities arising out of the Merger.

      The  causes of  action  in the IT  Litigation  relate  to the  actions  or
inactions of Sony under certain  agreements  entered into between IT and Sony in
April 1993, and as amended in November 1993 and October 1994 (collectively,  the
"Sony-IT  Agreement").  Pursuant to the original terms of the Sony-IT Agreement,
Sony was obligated,  among other things, to develop, produce, market, distribute
and exhibit three Cinematic Games. Subsequently,  at Sony's request, the Sony-IT
Agreement was amended so that Sony's  commitment to produce  Cinematic Games was
reduced to two Cinematic Games in exchange for, among other things, an increased
financial marketing  commitment by Sony. The first Sony-financed  Cinematic Game
was  initially  slated for release in the first half of 1994,  which release was
delayed until  February 1995.  Among other things,  IT alleges that the delay in
the opening of the first Cinematic Game,  which delay IT alleges was primarily a
result  of  Sony's  failure  to abide by the  terms  of the  Sony-IT  Agreement,
seriously harmed IT. Under the terms of the amended Sony-IT Agreement,  Sony was
obligated to begin  principal  photography of the next  Sony-financed  Cinematic
Game by May 15, 1995.

      In November 1996,  Sony asserted two  counterclaims  in the IT Litigation,
generally alleging that the Company's pre-Merger executives misrepresented their
qualifications  and breached the Sony-IT Agreement by not recruiting  sufficient
exhibitors.  The counterclaims  relate solely to the business  activities of the
Company  prior  to the  Merger.  A denial  of the  material  allegations  in the
counterclaims has been filed on behalf of the Company in the IT Litigation.  The
Partnership is obligated to indemnify the Company from certain claims, including
all liabilities and reasonable  expenses and costs that the Company may incur as
a result of the IT  Litigation,  and the  Company is closely  monitoring  the IT
Litigation.  The Company has incurred no  out-of-pocket  expenses in  connection
with the IT  Litigation.  The Company  believes  that the  Partnership's  assets
consist primarily of the IT Litigation, certain intellectual property assets and
cash assets of approximately  $75,000, with liabilities (primarily contingent on
a recovery in the IT Litigation) totaling approximately $731,500. Based upon the
opinion of the  Company's  counsel of record in the IT  Litigation,  the Company
believes that the counterclaims are without merit.  However,  the Company may be
liable in the event that a  judgment  is  rendered  against  the  Company on the
counterclaims,  and the  assets  of the  Partnership  may not be  sufficient  to
provide full indemnification.

      The Company is involved in various other claims and litigations arising in
the normal  course of  business,  consisting  of actions  commenced  against the
Company prior to the Merger. Management believes that the outcome of such claims
and litigation will not have a material adverse effect on the Company.

COMPENSATION OF DIRECTORS

      Pursuant to the 1996 Stock Option Plan,  which was adopted by the Board of
Directors subject to stockholder  approval,  each director of the Company who is
not an employee of the  Company or of a parent or  subsidiary  of the Company (a
"Non-Employee  Director") will be granted,  at the first meeting of the Board of
Directors  following each annual meeting of the stockholders of the Company,  an
option to purchase  10,000 shares of Common Stock at a per share  exercise price
equal to the fair market  value of a share of Common Stock on the date of grant,
which options are to vest as to 25% per of the option  granted during each year,
starting one year after the date of grant (a  "Non-Employee  Director's  Formula
Option").  Any  Non-Employee  Director  who is elected to the Board of Directors
after  August 28, 1996 and before the annual  stockholders'  meeting in any year
will also be granted a  Non-Employee  Director's  Formula  Option to  purchase a
pro-rata  portion of 10,000  shares equal to the portion of a year  (measured in
full calendar months)  remaining until the next scheduled  annual  stockholders'
meeting.  All Non-Employee  Directors serving on the date the Board of Directors
adopted the 1996 Stock Option Plan (Richard J. Murphy,  James T.  O'Brien,  John
K.A.  Prendergast  and  Michael S.  Weiss)  were  granted  initial  Non-Employee
Director's  Formula  Options to  purchase  20,000  shares of Common  Stock at an
exercise  price of $1.36  per share  with the same  exercise  price and  vesting
conditions as regular Non-Employee Director's Formula Options.

      Non-Employee  Directors  are paid  $12,000 per year,  plus  expenses,  for
services as a  director.  The Board of  Directors  agreed that in lieu of $4,000
which was due to each of the  Non-Employee  Directors as of December 1996,  such
directors may be granted a non-incentive stock option pursuant to the 1996 Stock
Option Plan,  subject to stockholder  approval of the 1996 Stock Option Plan, to
purchase  4,266 shares of Common Stock at an exercise price of $1.875 per share,
which was the fair market value per share on the date of grant. Such options are
immediately  exercisable  and expire ten (10) years from the date of grant.  Mr.
Murphy,  Mr.  O'Brien and Mr. Weiss were each granted such options.  The Company
paid no  compensation  to any  director  for  services as a director  during the
ten-month  period ended June 30, 1996.  Employee  directors  are not  separately
compensated for services as a director, but are reimbursed for expenses incurred
in performing their duties as directors, including attending all meetings of the
Board of  Directors  and any  committees  thereof.  Service as a  director  is a
condition of Edward J. Quilty's  employment  agreement,  but such service is not
separately compensated. See "Employment Agreements."

      In July 1996, the Company paid $36,000 to Buck A. Rhodes,  Ph.D., a former
director of the Company and RhoMed, as severance compensation for resigning from
the board of RhoMed  effective June 30, 1996. The  resignation and severance pay
were pursuant to the terms of a consulting  agreement dated as of March 7, 1996,
between RhoMed and Dr. Rhodes.

LIMITATION OF LIABILITY AND INDEMNIFICATION

      Section  145 of the  Delaware  General  Corporation  Law  provides  that a
corporation  may  indemnify any person who was or is a party or is threatened to
be  made a  party  to any  threatened,  pending  or  completed  action,  suit or
proceeding,  whether civil, criminal,  administrative or investigative by reason
of the fact  that he is or was a  director,  officer,  employee  or agent of the
corporation, or serving at the request of the corporation in similar capacities,
against expenses (including attorneys' fees), judgments, fines, and amounts paid
in settlement  actually and reasonably  incurred by him in connection  with such
action,  suit or  proceeding  if he  acted  in good  faith  and in a  manner  he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation,  and,  with respect to any criminal  action or  proceeding,  had no
reasonable  cause to believe his conduct was unlawful.  In the case of an action
or suit by or in the right of the corporation,  no indemnification shall be made
with  respect to any claim,  issue or matter as to which such person  shall have
been adjudged to be liable to the corporation unless and only to the extent that
the court having  jurisdiction  shall  determine  that such person is fairly and
reasonably entitled to indemnity.

      Article  V,  Section  3 of  the  Company's  Certificate  of  Incorporation
provides  that  to  the  fullest  extent   permitted  by  the  Delaware  General
Corporation  Law, no director of the Company shall be  personally  liable to the
Company or its  stockholders for monetary damages for breach of a fiduciary duty
as a director.

      Article VI of the Company's Certificate of Incorporation provides that the
Company  shall  make the  indemnification  permitted  under  Section  145 of the
Delaware General  Corporation Law, as summarized above, but only (unless ordered
by a court)  upon a  determination  by a majority  of a quorum of  disinterested
directors,  by  independent  legal  counsel  in a  written  opinion,  or by  the
stockholders,  that the  indemnified  person has met the applicable  standard of
conduct.  Article VI further  provides that the Company may advance expenses for
defending  actions,  suits or proceedings  upon such terms and conditions as the
Company's  Board of  Directors  deems  appropriate,  and that  the  Company  may
purchase  insurance on behalf of indemnified  persons whether or not the Company
would have the power to indemnify  such persons  under  Section 145 the Delaware
General Corporation Law.

      The  Company's  Bylaws  contain  substantially  the  same  indemnification
provisions as the Company's Certificate of Incorporation, summarized above.

      The  Company's  employment  agreement  with Edward J. Quilty  requires the
Company to indemnify  and advance  expenses to Edward J. Quilty,  the  Company's
Chairman of the Board,  President and Chief  Executive  Officer,  to the fullest
extent permitted under Section 145 of the Delaware General Corporation Law.

      The Company has obtained a directors'  and officers'  liability  insurance
policy which covers,  among other things,  certain liabilities arising under the
Securities Act.

      In the agreements pursuant to which the Company has registered the Offered
Shares (the  "Registration")  on Form SB-2 (the "Registration  Statement"),  the
Company has agreed,  to the extent  permitted by law, to indemnify  each Selling
Stockholder (with the exception of Bioquest Venture Leasing  Partnership  L.P.),
control persons of Selling Stockholders and underwriters of the Offered

                                      47

<PAGE>



Shares  against  liabilities  arising out of untrue  statements  or omissions of
material facts in the Registration  Statement or this Prospectus,  except to the
extent that the untrue  statement  or  omission is based on written  information
provided by the Selling Stockholder for inclusion in the Registration  Statement
or this  Prospectus.  Each Selling  Stockholder  (with the exception of Bioquest
Venture  Leasing  Partnership  L.P.) has agreed to indemnify  the  Company,  its
directors,  officers and control persons, and underwriters of the Offered Shares
against  liabilities  arising out of untrue  statements or omissions of material
facts in the Registration  Statement or this Prospectus,  but only to the extent
that the untrue statement or omission is based on written  information  provided
by the Selling  Stockholder for inclusion in the Registration  Statement or this
Prospectus.

      Insofar as  indemnification  for liabilities  arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised  that in the opinion of the  Securities  and  Exchange  Commission  such
indemnification  is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.

1996 STOCK OPTION PLAN

      The Board of Directors has adopted,  subject to stockholder approval,  the
1996 Stock Option Plan,  pursuant to which the Company may grant both  incentive
and  non-incentive  options to purchase up to 2,500,000  shares of Common Stock.
Except  for the  Non-Employee  Director's  Formula  Options  and  under  certain
circumstances  regarding acquisitions being made by the Company,  options are to
have exercise  prices not less than the fair market value of the Common Stock on
the date of grant.  Employees,  non-employee  directors and  consultants  of the
Company and its  subsidiaries to whom the Company grants options are eligible to
participate  in the 1996 Stock Option Plan.  As of the date of this  Prospectus,
the Company had granted  options to purchase an aggregate  of 739,798  shares of
Common Stock at exercise  prices  ranging from $1.36 to $2.00 per share.  If the
1996 Stock Option Plan is not approved by the stockholders,  the options already
granted  under the 1996 Stock  Option  Plan will  automatically  terminate.  See
"Description of Securities."

(1)   The  Company's  fiscal  year  ends  on June  30.  Due to a  change  in the
      Company's   fiscal  year  end,  fiscal  year  1996  covers  the  ten-month
      transition  period from  September 1, 1995 to June 30,  1996.  Fiscal year
      1995  ended  August 31,  1995  (RhoMed's  former  fiscal  year  end).  All
      references to  compensation  before June 25, 1996 (the Merger date) relate
      to compensation paid or issued by RhoMed.

(2) The security underlying all options is Common Stock.

(3)   Mr.  Quilty  became an employee and Chief  Executive  Officer of RhoMed on
      November  16, 1995 and became  Chief  Executive  Officer of the Company on
      June 25, 1996.

(4)   Includes  an  anti-dilution  option to purchase  281,031  shares of Common
      Stock at $.05 per share  granted on September  27,  1996,  pursuant to the
      terms  of  Mr.  Quilty's  employment   agreement  with  the  Company.  See
      "Employment Agreements" below. The September 27,

                                      49

<PAGE>



      1996  option  replaced a canceled  option to  purchase  the same number of
      shares at $1.36 per share,  originally  granted by RhoMed on June 21, 1996
      and included in the 1996 total.  The $1.36 per share price of the June 21,
      1996  option  was  not in  accordance  with  the  terms  of  Mr.  Quilty's
      employment agreement, so the Board of Directors replaced the June 21, 1996
      option with the correctly priced September 27, 1996 option. Excluding that
      replacement  option,  the  options  granted  during  fiscal  1997  were to
      purchase a total of 679,270 shares.

(5)   Dr.  Spana  became an employee of RhoMed on June 15, 1996 and an Executive
      Vice President of the Company on June 25, 1996. Before becoming an officer
      of the Company, he was a consultant to RhoMed.

(6) Consists of consulting fees paid by RhoMed.

(7)   Mr. Putnam became an employee of RhoMed on June 3, 1996 and an Executive 
      Vice President of the Company on June 25, 1996.

EMPLOYMENT AGREEMENTS

     Executive  officers of the Company are  appointed by the Board of Directors
and serve at the  discretion of the Board of Directors.  Each officer shall hold
his position  until his successor is appointed and qualified.  Mr.  Quilty,  Dr.
Spana and Mr. Putnam each hold their offices pursuant to employment agreements.

      Subsequent to the Merger, the Company adopted, with amendments as required
to reflect the Merger, an employment agreement entered into on November 16, 1995
between RhoMed and Edward J. Quilty.  Pursuant to this agreement,  Mr. Quilty is
serving as President and Chief Executive Officer of the Company and RhoMed.  The
initial term of the  employment  agreement was one year and it is  automatically
renewed for  successive  twelve-month  periods unless either party gives written
notice to the  contrary,  or unless the agreement is otherwise  terminated.  Mr.
Quilty's  minimum  base  salary is  $300,000  per year;  his  current  salary is
$321,000 per year.  The Company has agreed to reimburse  Mr. Quilty for premiums
and other payments to maintain a $1,000,000 term life insurance policy issued in
1992 for the  benefit  of Mr.  Quilty  and his  designees.  Mr.  Quilty may also
participate  in any benefit  plans  available to other senior  executives of the
Company,  and in any  directors'  and officers'  liability  insurance  which the
Company maintains.  Pursuant to the employment  agreement,  RhoMed issued to Mr.
Quilty an option to purchase  common stock equal to a 10% fully  diluted  equity
interest in RhoMed as of November  16, 1995,  at a price of $0.01 per share,  to
vest in 36 equal increments monthly during the term of the employment agreement.
By operation of the Merger,  that option became an option for 431,266  shares of
Common  Stock at an  exercise  price of $0.05 per share  (rounded to the nearest
cent). To date, Mr. Quilty has exercised that option as to 191,673  shares.  The
agreement also provides for anti-dilution protections which, among other things,
require the Company to issue additional  options with the same exercise price as
the original option, so that Mr. Quilty shall, at all times, have options in the
aggregate to purchase the number of shares of Common Stock (together with Common
Stock purchased on the exercise of such options) equal to not less than 3.75% of
the Company's outstanding Common Stock on a fully diluted basis. Pursuant to the
anti-dilution  protections,  the  Company  has issued to Mr.  Quilty  additional
anti-dilution  options to  purchase  an  aggregate  of 611,199  shares of Common
Stock,  which  options vest in equal  monthly  increments  so as to become fully
vested 36 months  after the  commencement  of the  employment  agreement.  For a
period of five (5) years after the first  anniversary  of the Company's  initial
post-Merger public offering, Mr. Quilty has piggy-back registration rights as to
all  Common  Stock  which he owns.  If the  Company  terminates  the  employment
agreement for "cause," or if Mr. Quilty  terminates the agreement  without "good
reason," then the  Company's  payment  obligation  is limited to amounts  earned
through the  termination  date, and the option will be  exercisable  only to the
extent  vested.  If Mr.  Quilty  elects to terminate  the  employment  agreement
following a  post-Merger  change in control of the Company,  then the  Company's
payment  obligation is limited to amounts earned through the  termination  date,
but the option  will  immediately  become  exercisable  in full.  If the Company
terminates  the  employment  agreement  without  cause,  or in the  event of Mr.
Quilty's  death  or  disability,  or if Mr.  Quilty  terminates  the  employment
agreement  with good  reason,  then in  addition to amounts  earned  through the
termination  date,  the Company must pay Mr. Quilty one year of his then current
base salary. "Cause," as defined in the employment agreement, consists of fraud,
felony conviction,  refusal to carry out instructions of the Board of Directors,
or governmental

                                      52

<PAGE>



disqualification (all as defined in the employment agreement). "Good reason," as
defined in the  employment  agreement,  consists of breach by the Company of its
obligations  under the  employment  agreement.  The  employment  agreement  also
includes non-competition, confidentiality and indemnification covenants.

      Carl Spana,  Ph.D.,  and Charles Putnam have each entered into  employment
agreements with the Company dated September 27, 1996,  pursuant to which each is
serving as an Executive  Vice  President of the Company for a three-year  period
commencing  June 21, 1996.  Effective June 21, 1997, the base salary for each is
$160,500  per year.  Each is  entitled to  participate  in all bonus and benefit
programs  that the  Company  establishes,  to the extent his  position,  tenure,
salary,  age, health and other  qualifications make him eligible to participate.
Each  agreement  allows  either the  Company or the  employee to  terminate  the
agreement  on thirty  (30) days'  notice,  and  contains  other  provisions  for
termination  by the Company for "cause," or by the  employee  for "good  reason"
after a "change in control"  (all as these  terms are defined in the  respective
agreements). Early termination may, in some circumstances, result in accelerated
vesting of stock options  and/or  severance  pay for a nine-month  period at the
rate of base salary,  cash bonus and  benefits  then in effect.  Each  agreement
contains non-competition and confidentiality covenants.

                             CERTAIN TRANSACTIONS

     In  November  1996,  the  Company  engaged  the  Placement  Agent to act as
exclusive  placement  agent  for  the  Series  A  Offering.  Mr.  Weiss  and Dr.
Prendergast,  directors of the Company,  recused  themselves  from voting on the
matter,  and the Series A Offering was  approved by a vote of the  disinterested
directors.  Mr. Weiss is an officer of the Placement Agent and Paramount Capital
Investments,  an  affiliate  of the  Placement  Agent,  and Dr.  Prendergast  is
Managing  Director of Paramount  Capital  Investments.  As placement  agent, the
Placement  Agent  received a 9% commission,  amounting to  $1,240,020,  and a 4%
non-accountable expense allowance,  amounting to $551,120, on the gross proceeds
of the Series A Offering,  for an aggregate  total of $1,791,140,  and Preferred
Stock  Placement  Warrants to  purchase  13,778  shares of Series A  Convertible
Preferred  Stock,  at an exercise  price of $110 per share offering  price.  The
Company  also  agreed  to  indemnify   the  Placement   Agent  against   certain
liabilities,   including  liabilities  arising  under  the  Securities  Act,  in
connection with the Series A Offering.

      Pursuant to the placement agency agreement for the Series A Offering,  the
Company  entered into an  introduction  agreement with the Placement  Agent (the
"Introduction Agreement"), under which the Placement Agent acts as the Company's
non-exclusive  financial  advisor for a minimum  period of eighteen  (18) months
commencing January 1, 1997, and will receive (i) out-of-pocket expenses incurred
in connection with services performed under the Introduction  Agreement,  (ii) a
retainer of $72,000 and (ii)  percentage  or lump sum success  fees in the event
that the Placement

                                      59

<PAGE>



Agent  assists the Company in  connection  with certain  financing and strategic
transactions.  The Introduction Agreement replaced a similar agreement in effect
from  September  1,  1996  through  December  31,  1996,  pursuant  to which the
Placement  Agent  received  a  retainer  of $5,000  per  month and a warrant  to
purchase 25,000 shares of Common Stock at $2.25 per share.

      Prior to the Merger,  the Placement Agent served as placement agent for an
offering of shares of RhoMed common stock (the "RhoMed  Common Stock  Offering")
authorized by RhoMed's  board of directors on March 4, 1996;  the RhoMed Class B
Offering authorized by RhoMed's board of directors on November 27, 1995; and the
RhoMed Class A Offering  authorized  by RhoMed's  board of directors on July 28,
1995. In the RhoMed Class A Offering, the RhoMed Class B Offering and the RhoMed
Common Stock Offering,  RhoMed paid the Placement Agent  commissions and fees of
$90,000,  $110,500  and  $1,253,902,  respectively,  and issued  warrants to the
Placement Agent to purchase RhoMed common stock, which as a result of the Merger
were converted into warrants to purchase  82,949 shares of Common Stock at $0.05
per share;  7,834 shares of Common Stock at $1.63 per share;  and 711,184 shares
of Common Stock at $1.63 per share, respectively.

      Effective  April 1995,  RhoMed entered into a letter of intent with Castle
Group under which (i) Castle  Group agreed to arrange for a line of credit of up
to $300,000 to finance ongoing operations of RhoMed; (ii) Castle Group agreed to
arrange for future  financings  for RhoMed;  and (iii) RhoMed  agreed to sell to
Castle Group or its designees,  for nominal  consideration,  4,000,000 shares of
RhoMed Series A Convertible  Preferred Stock. This resulted,  at the time of the
investment,  in Castle Group and affiliates of Castle Group  obtaining  majority
ownership and control of RhoMed.  Castle Group is owned by Lindsay A. Rosenwald,
M.D.,  and is under common  control with the  Placement  Agent.  Pursuant to the
letter of intent,  RhoMed borrowed the maximum amount,  and paid off the line of
credit in full in  September  1995.  The average  interest  rate for the line of
credit was 10.90% and the total interest paid was $8,005.

      On July 24, 1995,  Michael S. Weiss and Carl Spana,  Ph.D., were appointed
to the board of  directors  of RhoMed.  Dr.  Spana was an employee of  Paramount
Capital  Investments  at the  time  of his  appointment  to  RhoMed's  board  of
directors.   The  RhoMed  Class  A  Offering   was  ratified  by   disinterested
stockholders  of RhoMed on August  15,  1995;  the RhoMed  Class B Offering  was
approved by disinterested directors with Mr. Weiss and Dr. Spana abstaining; and
the  placement  agent for the RhoMed  Common  Stock  Offering was selected by an
offering  committee of RhoMed's board of directors,  consisting of disinterested
directors.

      As a result of the RhoMed offerings  described above, Dr.  Rosenwald,  Mr.
Weiss, and Dr. Spana received equity  securities of the Company in the following
amounts:  Dr.  Rosenwald  received  warrants to purchase 60,319 shares of Common
Stock at $0.05 per share and warrants to purchase 205,664 shares of Common Stock
at $1.63 per share; RAQ, LLC, a company  controlled by Dr.  Rosenwald,  received
1,657,070  shares of Common Stock;  Mr. Weiss  received  51,702 shares of Common
Stock,  warrants to purchase 5,858 shares of Common Stock at $0.05 per share and
warrants to purchase  40,495 shares of Common Stock at $1.63 per share;  and Dr.
Spana received 46,695 shares of Common Stock.

     Dr.  Rosenwald is the president and sole  stockholder of Paramount  Capital
Asset  Management,  Inc.,  the  general  partner  of  Aries  Domestic  Fund  and
investment manager of The Aries Trust

                                      60

<PAGE>



(together,  the "Aries  Entities").  The Aries Entities taken together purchased
the following equity securities: 10,000 shares of Series A Convertible Preferred
Stock,  convertible  into 806,451  shares of Common Stock,  1,290,696  shares of
Common  Stock,  warrants to purchase  18,433  shares of Common Stock at $.68 per
share, and warrants to purchase 55,299 shares of Common Stock at $.05 per share.
Following the RhoMed Common Stock Offering,  the Placement Agent assigned to the
Aries Entities those portions of the Placement  Agent's placement agent warrants
attributable to the Common Stock purchases of the Aries Entities,  consisting of
warrants to purchase 129,068 shares of Common Stock at $1.63 per share.

     Mr.  Quilty,  Dr. Spana,  Mr. Putnam and  Non-Employee  Directors have been
granted  options  to  purchase  Common  Stock.  See   "Management,"   "Executive
Compensation" and "Principal Stockholders."

      Buck A. Rhodes,  Ph.D. was a director of RhoMed from inception  until June
30, 1996, was President of RhoMed from inception  until March 7, 1996, and was a
director  of the Company  from June 25,  1996  through  June 30,  1996.  Under a
consulting  agreement  dated March 7, 1996  between Dr.  Rhodes and RhoMed,  Dr.
Rhodes was paid $51,023 in accrued salary and $36,000 as severance  compensation
for resigning from the board of RhoMed,  and is being paid $6,833 per month from
April 1996 through March 1998 for consulting services.



                           DESCRIPTION OF SECURITIES

      The Company is authorized to issue  25,000,000  shares of Common Stock and
2,000,000  shares of Preferred  Stock.  The Board of  Directors  has adopted and
submitted to  stockholders  for approval at the special  meeting of stockholders
scheduled  for  August  21,  1997 (the  "Special  Meeting"),  amendments  to the
Company's  Certificate of Incorporation  which would (i) increase the authorized
shares  of  Common  Stock to  75,000,000  shares  and the  authorized  shares of
Preferred Stock to 10,000,000  shares;  and (ii) effect a reverse stock split of
the Common Stock (such split to combine a number of outstanding shares of Common
Stock between two (2) and four (4), such number  consisting of only whole shares
and  tenths of shares,  into one (1) share of common  stock),  depending  upon a
determination  by the Board of Directors  that such a reverse  stock split is in
the best interests of the Company and its stockholders,  and authorize the Board
of Directors to file one such amendment prior to December 31, 1997. The Board of
Directors  has also adopted and  submitted to  stockholders  for approval at the
Special Meeting the 1996 Stock Option Plan which authorizes the Company to issue
stock  options for up to 2,500,000  shares of Common Stock (of which  options to
purchase  739,798  shares have  previously  been granted  subject to stockholder
approval of the 1996 Stock Option Plan).

COMMON STOCK

      As of the date of this Prospectus,  there are 12,164,444  shares of Common
Stock  outstanding,  and a maximum of 16,549,857 shares of Common Stock issuable
on conversion  or exercise of securities  convertible  into or  exercisable  for
Common  Stock.  Holders  of  Common  Stock  have one vote per  share and have no
preemption rights. Holders of Common Stock have the right to participate ratably
in all distributions, whether of dividends or assets in liquidation, dissolution
or

                                      61

<PAGE>



winding up,  subject  to  any  superior  rights of  holders of  Preferred  Stock
outstanding  at the time.  See  "Preferred  Stock"  and  "Series  A  Convertible
Preferred Stock."

PREFERRED STOCK

      The Board of  Directors  has the right,  without the consent of holders of
Common  Stock,  to designate  and issue one or more series of  Preferred  Stock,
which may be convertible into Common Stock at a ratio determined by the Board of
Directors,  and which may bear  rights  superior  to Common  Stock as to voting,
dividends, redemption, distributions in liquidation, dissolution, or winding up,
and other relative rights and preferences. The issuance of a series of Preferred
Stock in response to an attempt to change  control of the Company could have the
effect of delaying,  deferring or preventing the change in control.  The holders
of  the  Series  A  Convertible  Preferred  Stock  have  special  voting  rights
(described  below)  which  could  have the  effect  of  delaying,  deferring  or
preventing a change in control  without the consent of two-thirds of the holders
of Series A Convertible Preferred Stock then outstanding.

SERIES A CONVERTIBLE PREFERRED STOCK

      The Board of Directors  has  established  one series of 264,000  shares of
Preferred  Stock,  the Series A Convertible  Preferred  Stock,  of which 137,780
shares are  outstanding  and 13,778  shares are  issuable  upon  exercise of the
Preferred Stock Placement Warrants. The Series A Convertible Preferred Stock has
the rights and preferences set forth below.

      OPTIONAL CONVERSION. Each share of Series A Convertible Preferred Stock is
convertible at any time, at the option of the holder,  into the number of shares
of Common Stock equal to $100 divided by the  "Conversion  Price" (as defined in
the Certificate of Designations for the Series A Convertible  Preferred  Stock).
The current  Conversion  Price is $1.24,  so each share of Series A  Convertible
Preferred  Stock is  currently  convertible  into  approximately  80.6 shares of
Common Stock  (fractional  shares will be cashed out on  conversion,  and do not
vote).  The Conversion  Price is subject to  adjustment.  As of the date of this
Prospectus, no holder has converted any Series A Convertible Preferred Stock.

      MANDATORY  CONVERSION.  Commencing  May 9, 1998,  the Company  may, at its
option,  cause the conversion of the Series A Convertible  Preferred  Stock,  in
whole or in part, on a pro rata basis,  into Common Stock at the conversion rate
in  effect at that  time,  if the  closing  bid  price of the  Common  Stock has
exceeded 200% of the then applicable  Conversion  Price for at least twenty (20)
trading days in any thirty (30) consecutive  trading day period ending three (3)
days prior to the date of conversion.

      ADJUSTMENTS TO THE CONVERSION  PRICE.  The Conversion  Price is subject to
adjustment,  under  certain  circumstances,  upon the sale or issuance of Common
Stock for  consideration  per share less than either (i) the Conversion Price in
effect on the date of such sale or  issuance,  or (ii) the  market  price of the
Common Stock as of the date of such sale or issuance.  The  Conversion  Price is
also subject to  adjustment  upon the  occurrence  of a merger,  reorganization,
consolidation, reclassification, stock dividend or stock split which will result
in an increase or decrease in the number of shares of Common Stock outstanding.

                                      62

<PAGE>



      CONVERSION   PRICE  RESET  EVENT.  The  Conversion  Price  is  subject  to
adjustment on May 9, 1998 (the "Reset Date") if the average closing bid price of
the Common  Stock for the  thirty  (30)  consecutive  trading  days  immediately
preceding  the Reset Date (the "Reset  Trading  Price") is less than 130% of the
then  applicable  Conversion  Price (a "Reset Event").  Upon a Reset Event,  the
Conversion  Price will be reduced  to  greater  of (i) the Reset  Trading  Price
divided by 1.3 or (ii) 50% of the  Conversion  Price in effect  before the Reset
Event.

      REPURCHASE OR CASH-OUT  OPTION.  In the event that the Company has not, by
February 3, 1998,  authorized a  sufficient  number of shares of Common Stock to
permit  conversion in full of all  outstanding  Series A  Convertible  Preferred
Stock, then each holder will be entitled, at the holder's option, to require the
Company to  repurchase  the holder's  shares of Series A  Convertible  Preferred
Stock at $100 per share.  In the event that on the date when a holder  elects to
convert,  the Company has not authorized a sufficient number of shares of Common
Stock  to  permit  conversion  in  full of the  holder's  Series  A  Convertible
Preferred Stock,  then the holder will be entitled,  at the holder's option,  to
receive the fair market  value per share of Common  Stock which the holder would
have received,  if the Company had authorized  sufficient Common Stock to permit
the conversion.

      DIVIDEND AND DISTRIBUTION  PREFERENCE.  The Company may not pay a dividend
or make any  distribution  to holders of any other  capital stock of the Company
unless and until the Company first pays a special  dividend or  distribution  of
$100 per share to the  holders  of Series A  Convertible  Preferred  Stock,  and
unless holders of two-thirds of the Series A Convertible Preferred Stock approve
the dividend.

      LIQUIDATION PREFERENCE. Upon (i) a liquidation,  dissolution or winding up
of  the  Company,  whether  voluntary  or  involuntary,  (ii) a  sale  or  other
disposition of all or substantially  all of the assets of the Company,  or (iii)
any consolidation,  merger, combination,  reorganization or other transaction in
which the Company is not the  surviving  entity or in which the shares of Common
Stock  constituting  in excess of 50% of the  voting  power of the  Company  are
exchanged for or changed into other stock or  securities,  cash and/or any other
property,  after  payment  or  provision  for  payment  of the  debts  and other
liabilities of the Company, the holders of Series A Convertible  Preferred Stock
then outstanding  will first be entitled to receive,  pro rata and in preference
to the  holders of any other  capital  stock,  an amount per share equal to $100
plus accrued but unpaid dividends, if any.

      VOTING RIGHTS. Each holder of Series A Convertible Preferred Stock has the
number of votes  equal to the  number of shares of Common  Stock  issuable  upon
conversion of the holder's  Series A Convertible  Preferred  Stock at the record
date for  determination  of the  stockholders  entitled to vote or, if no record
date is  established,  at the date a vote is taken. So long as a majority of the
Series A Convertible  Preferred Stock outstanding as of May 9, 1997 and issuable
upon exercise of the Placement Agent's Warrants remain  outstanding or issuable,
the approval of holders of 66-2/3% of the Series A Convertible  Preferred  Stock
then  outstanding  is required for (i) any  alteration of the Company's  charter
documents  or  bylaws  that  would   adversely   affect  the  relative   rights,
preferences,  qualifications,  limitations  or  restrictions  of  the  Series  A
Convertible  Preferred Stock; (ii) the declaration or payment of any dividend on
any other  securities or the  repurchase of any  securities of the Company other
than the  Series A  Convertible  Preferred  Stock;  and (iii)  authorization  or
issuance,  or increase the authorized  amount of, any security  ranking prior to
the Series A Convertible Preferred

                                      63

Stock as to liquidation, payment of dividends or distributions or voting rights.

                             PLAN OF DISTRIBUTION

      REGISTRATION.   The  Company  has  effected  the  Registration  under  the
Securities Act on behalf of the Selling  Stockholders,  pursuant to registration
rights  contained in the agreements by which each Selling  Stockholder  acquired
Offered Shares or securities convertible into or exercisable for Offered Shares.
The Company will pay all expenses of the  Registration,  and of qualification or
exemption of the Offered Shares under state securities  laws,  excluding fees of
legal counsel for Selling Stockholders. The Company is obligated to use its best
efforts to keep the Registration  effective until the Selling  Stockholders have
completed  the  distribution  described in this  Prospectus.  Whether or not the
Selling Stockholders have completed the described distribution,  the Company may
cease to keep the Registration effective with respect to a Selling Stockholder's
Offered  Shares at any time when such Selling  Stockholder  may sell all of such
Selling Stockholder's Offered Shares under Rule 144 under the Securities Act (or
other  exemption  from  the  registration  requirements  of the  Securities  Act
acceptable to the Company) in a three-month period.

     SALES OF THE OFFERED SHARES. Selling Stockholders may, but are not required
to, sell  Offered  Shares from time to time  directly to  purchasers  or through
underwriters,  brokers,  dealers or agents.  Selling  Stockholders  will pay any
underwriting  discounts  or  commissions  applicable  to the sale of the Offered
Shares.  Selling  Stockholders may sell Offered Shares on a securities exchange,
in the over-the-counter  market, in privately negotiated  transactions,  or in a
combination  of these  methods,  without  notice  to the  Company.  If a Selling
Stockholder  intends to sell Offered Shares by any other method or  transaction,
the Selling Stockholder must give the Company notice at least five business days
in advance. Selling Stockholders must sell Offered Shares in accordance with the
Registration Statement and must comply with the prospectus delivery requirements
of the Securities Act.  Selling  Stockholders  must  discontinue  disposition of
Offered Shares during certain  limited  periods when (i) the Company is required
to  supplement  or amend this  Prospectus,  (ii) the  Company is  engaging  in a
primary underwritten  offering,  or (iii) the Company determines that disclosure
of  material  undisclosed  information  required in a  prospectus  would have an
adverse effect on the Company or is otherwise inadvisable.

      Selling  Stockholders and any broker-dealers  that participate in the sale
of the Offered Shares may be deemed to be  "underwriters"  within the meaning of
Section 2(11) of the Securities Act and any commission  received by them and any
profit on the  resale of the  Offered  Shares as  principal  may be deemed to be
underwriting discounts and commissions under the Securities Act.

      The Company has, as of the date of this  Prospectus,  informed the Selling
Stockholders that no National  Association of Securities Dealers ("NASD") member
participating  in the Offering may receive  compensation  in excess of 8% of the
proceeds of the sale of Offered Shares. In addition, the

                                      75

<PAGE>



terms and arrangements of any underwritten  offering must be filed with the NASD
for its review pursuant to Section 2710 of the NASD's Corporate Financing Rules.

      The Company has, as of the date of this  Prospectus,  informed the Selling
Stockholders that the  anti-manipulation  provisions of Regulation M promulgated
under the  Exchange  Act may apply to the sales of  Offered  Shares,  and of the
requirement  for delivery of this  Prospectus in connection with any sale of the
Offered  Shares.  Certain  Selling  Stockholders  may from time to time purchase
shares of Common  Stock in the open  market.  The Company has, as of the date of
this Prospectus, informed the Selling Stockholders that they should not commence
any  distribution  of the  Offered  Shares  unless  they have  terminated  their
purchasing  of, bidding for and attempting to induce any other person to bid for
or purchase Common Stock in the open market as provided in applicable securities
regulations, including Regulation M.

      LOCK-UP  AGREEMENT.  The Offered  Shares which are issued on conversion of
shares of Series A  Convertible  Preferred  Stock  other  than  those  issued on
exercise of  Preferred  Stock  Placement  Warrants  (the  "Lock-up  Shares") are
subject to a partial,  diminishing  lock-up  agreement for up to nine (9) months
after the effective date of the Registration  Statement (the "Effective  Date").
Without the prior  written  consent of the Placement  Agent,  holders of Lock-up
Shares may not directly or indirectly  sell or otherwise  dispose of the Lock-up
Shares according to the following schedule: 75% of Lock-up Shares are subject to
lock-up until three (3) months after the Effective  Date;  50% of Lock-up Shares
are subject to lock-up  until six (6) months after the  Effective  Date;  25% of
Lock-up  Shares are subject to lock-up until nine (9) months after the Effective
Date;  and the  remaining  25% of the  Lock-up  Shares  are not  subject  to any
restriction.



                                 LEGAL MATTERS

      Legal matters relating to the Offering will be passed upon for the Company
by Rubin Baum Levin  Constant &  Friedman,  New York,  New York,  counsel to the
Company.  Members  of Rubin Baum Levin  Constant  & Friedman  have been  granted
options under the 1996 Stock Option Plan (subject to stockholder approval of the
1996 Stock  Option  Plan) to purchase an  aggregate  of 50,000  shares of Common
Stock  at an  exercise  price  of $2.00  per  share.



                                    EXPERTS

     The financial statements for the ten-month transition period ended June 30,
1996   (post-Merger)   and  for  the  years  ended  August  31,  1995  and  1994
(pre-Merger),  included in this  Prospectus and in the  Registration  Statement,
have been audited by Arthur Andersen LLP,  independent  public  accountants,  as
indicated  in their report with  respect  thereto,  and are included in reliance
upon the authority of Arthur Andersen LLP as experts in giving said report.

                             CHANGES IN ACCOUNTANTS


      As of July 9, 1996, in connection with the Merger,  Deloitte & Touche LLP,
the  Company's  independent  accountant  which  was  engaged  as  the  principal
accountant to audit the  Company's  financial  statements,  was  dismissed.  The
Company,  after  consultation  with Arthur Andersen LLP, engaged Arthur Andersen
LLP as of July 9,  1996 as the  principal  accountant  to  audit  the  Company's
financial  statements.  Arthur  Andersen  LLP  served  as  RhoMed's  independent
accountant prior to the Merger.

      RhoMed,  prior to the Merger,  consulted Arthur Andersen LLP regarding the
application of accounting  principles to the proposed Merger.  The primary issue
that was the  subject  of such  consultations  was the  characterization  of the
proposed  Merger for  accounting  purposes.  RhoMed was orally advised by Arthur
Andersen  LLP that the Merger would be treated as a  recapitalization  of RhoMed
with RhoMed as the acquirer (reverse acquisition),  and that the proposed Merger
would not constitute a business  combination.  The Company's former  accountant,
Deloitte & Touche LLP, was not consulted by the Company regarding such issue.

      The Company's  decision to change accountants was recommended and approved
by the  Company's  Board of  Directors  subsequent  to the Merger based upon the
Company's  need  for  one  independent  accountant  to be  responsible  for  the
financial  statements of the Company  following the Merger.  During  Interfilm's
fiscal  years  ended  December  31, 1995 and 1994,  there were no  disagreements
between the Company and Deloitte & Touche LLP, the Company's former  independent
accountant,  on any matter of  accounting  principles  or  practices,  financial
statement  disclosure,   or  auditing  scope  or  procedure.   Further,   during
Interfilm's  fiscal  years  ended  December  31,  1995 and  1994,  respectively,
Deloitte  &  Touche  LLP's  opinion  with  respect  to the  Company's  financial
statements  was  qualified  as to the  Company's  ability to continue as a going
concern.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Stockholders and Board of Directors of
     Palatin Technologies, Inc.:


We have audited the accompanying consolidated balance sheets of PALATIN
TECHNOLOGIES, INC. (a Delaware corporation in the development stage) AND
SUBSIDIARIES as of June 30, 1996 (post-Merger, see Note 1) and August 31, 1995
(pre-Merger), and the related consolidated statements of operations,
stockholders' equity (deficit) and cash flows for the period from September 1,
1995 through June 30, 1996 (post-Merger, consisting of the statement of
operations and cash flows of RhoMed Incorporated, predecessor corporation in
the continuing business of Palatin Technologies, Inc. and subsidiaries for the
period from September 1, 1995 through June 25, 1996 (pre-Merger), audited by
us,
and the statements of operations and cash flows of Palatin Technologies, Inc.
and subsidiaries for the period from June 26, 1996 through June 30, 1996
(post-Merger), also audited by us, and for the years ended August 31, 1995 and
1994 (pre-Merger). We have also audited the consolidated statements of
operations and cash flows of Palatin Technologies, Inc. and subsidiaries for
the period from inception (January 28, 1986) through June 30, 1996
(post-Merger, consisting of the statements of operations and cash flows of
RhoMed Incorporated and Palatin Technologies, Inc. and subsidiaries as
described above). These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

                                      F-1

subsidiaries as of June 30, 1996, and August 31, 1995, and the results of their
operations and their cash flows for each of the periods indicated above in
conformity with generally accepted accounting principles.

                          PALATIN TECHNOLOGIES, INC.
          (RhoMed Incorporated prior to June 25, 1996 Reverse Merger)
                       (A Development Stage Enterprise)
                  Notes to Consolidated Financial Statements
               for the Period from Inception (January 28, 1986)
              through June 30, 1996 and for the Ten Months Ended
          June 30, 1996 and the Years Ended August 31, 1995 and 1994

(1)     ORGANIZATION ACTIVITIES:

        Corporate Structure -- Palatin Technologies, Inc. ("Palatin"),
formerly Interfilm, Inc., was incorporated under the laws of the State of
Delaware on November 21, 1986. Since November 4, 1993, when Palatin acquired
Interfilm Technologies, Inc., a New York corporation, it had been primarily
engaged in the business of exploiting the rights related to its interactive
motion picture process, including the production and distribution of
interactive motion pictures for initial exhibition in theaters and
subsequently in enhanced versions for distribution to the home market.
Palatin's initial public offering was consummated on October 28, 1993. On May
10, 1995, the Board of Directors of Palatin decided to substantially curtail
the operations of Palatin and its subsidiaries.

        Merger -- On June 25, 1996, a newly formed, wholly-owned subsidiary of
Palatin, Interfilm Acquisition Corporation ("InSub"), a New Mexico
corporation, merged with and into RhoMed Incorporated ("RhoMed"), a New Mexico
corporation, with all outstanding shares of RhoMed equity securities
ultimately being exchanged for Palatin's common stock (the "Merger"). As a
result of the Merger, RhoMed became a wholly-owned subsidiary of Palatin, with
the holders of RhoMed preferred stock and RhoMed common stock (including the
holders of "RhoMed Derivative Securities" as hereafter defined) receiving an
aggregate of approximately 96% interest in the equity securities of Palatin on
a fully-diluted basis. Additionally, all warrants and options to purchase
common stock of RhoMed outstanding immediately prior to the Merger (the
"RhoMed Derivative Securities"), including without limitation, any rights
underlying RhoMed's qualified or nonqualified stock option plans, were
automatically converted into rights upon exercise to receive Palatin's common
stock in the same manner in which the shares of RhoMed common stock were
converted. Since the former stockholders of RhoMed retained more than a 50%
controlling interest in the surviving company (Palatin), the Merger was
accounted for as a reverse merger. Certain assets and liabilities of Palatin
and a subsidiary existing prior to the Merger, consisting principally of
certain intellectual property and litigation claims against Sony Corporation
of America and related entities, were transferred to an unaffiliated limited
liability partnership for the benefit of Palatin stockholders of record as of
June 21, 1996, immediately prior to the Merger. Pro forma combined operating
results of the merged companies are not presented since the reverse merger is
not a business combination for accounting purposes. The historical financial
statements prior to June 25, 1996, are those of RhoMed, except that the net
loss per common share has been stated on an as if converted basis. In
addition, the Merger costs of $450,000 have been charged to operations for the
ten months ended June 30, 1996, and accrued expenses include $231,635 of this
amount as of June 30, 1996.

        On July 19, 1996, an amendment to the Certificate of Incorporation of
Palatin (the "Amendment") was filed, which (a) effected the change of name
from Interfilm, Inc. to Palatin Technologies, Inc., (b) increased the total
number of authorized shares of Palatin's common stock, par value $.01 per
share (the "Common Stock"), from 10,000,000 to 25,000,000, and (c) effected a
1-for-10 reverse split of Common Stock. Upon the filing of the Amendment, each
share of RhoMed preferred stock was

                                     F-10

converted into .46695404349 shares of Common Stock, and each share of RhoMed
common stock was converted into .184332593 shares of Common Stock. The
consolidated financial statements have been adjusted to reflect the Amendment
as if it had been filed on June 30, 1996.

        Nature of Business -- Palatin, through its wholly-owned subsidiary,
RhoMed, is a development stage enterprise dedicated to developing and
commercializing products and technologies for diagnostic imaging, cancer
therapy and ethical drug development based upon its proprietary monoclonal
antibody, radiolabeling and enabling peptide platform technologies. Palatin
had, prior to June 25, 1996, conducted no on-going business activities since
May 10, 1995. The business of RhoMed, conducted by Palatin since June 25,
1996, when the Merger became effective, represents the on-going business of
Palatin.

        Since its inception, RhoMed has devoted substantially all of its
efforts and resources to the research and development of its technology.
RhoMed has experienced operating losses in each year since its inception and,
as of June 30, 1996, Palatin, including its wholly-owned subsidiary RhoMed,
had a deficit accumulated during the development stage of $8,132,938. Palatin
expects to incur additional operating losses over the next several years and
expects cumulative losses to increase as Palatin's research and development
and clinical testing efforts continue and expand. The ultimate completion of
Palatin's development projects is contingent upon a number of factors,
including the successful completion of technology and product development,
obtaining required regulatory approvals and additional financing and,
ultimately, achieving profitable operations.

        Change in Fiscal Year -- Effective June 30, 1996, Palatin and RhoMed
each changed its fiscal year end to June 30. The fiscal year ends of Palatin
and RhoMed prior to the Merger were December 31 and August 31, respectively.

(2)     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

        Principles of Consolidation -- The consolidated financial statements
include the accounts of Palatin and its wholly owned subsidiary, RhoMed. The
remaining subsidiaries of Palatin - Interfilm Technologies, Inc., Ediflex
Digital Systems, Inc. and Production Equipment Leasing Corp. LP - are
inactive. All significant intercompany accounts and transactions have been
eliminated in consolidation.

        Accounting Basis -- The financial books and records of Palatin are
maintained on the accrual basis of accounting. As a development stage
enterprise, cumulative results of operations from inception are presented.

        Cash -- For purposes of presenting cash flows, Palatin considers cash
as amounts on hand, on deposit in financial institutions and highly liquid
investments purchased with an original maturity of three months or less.

        Equipment -- Equipment and office furniture are stated at cost, net of
accumulated depreciation. Depreciation is recognized using an accelerated
method over the estimated useful lives of 5 years for equipment, 7 years for
office furniture and over the term of the lease for leasehold improvements.
Maintenance and repairs are expensed as incurred while expenditures that
extend the useful life of an asset are capitalized.

        Patents -- Patents represent the costs capitalized to successfully
obtain a patent registration. Internal costs to obtain and develop the patents
have been expensed. Patents are included as intangible assets in the
accompanying consolidated financial statements and are stated at cost, net of
accumulated amortization. Amortization is recognized using the straight-line
method over the estimated patent lives

                                     F-11
<PAGE>


ranging up to 17 years.  Unsuccessful patent costs and patents with no
demonstrated future value are expensed when so determined by management.

     Revenue Recognition -- The Company recognizes revenue as follows: grants
and contracts - at the time such related expenses are incurred in compliance
with contractual terms; license fees and royalties - ratably over the term of
the license or royalty agreement; and sales - upon shipment of the product.

     Research and Development Costs -- The costs of research and development
activities are expensed as incurred.

     Stock Options and Warrants -- Warrants and most common stock options have
been issued at exercise prices greater than, or equal to, their fair market
value at the date granted.  Accordingly, no value has been assigned to these
instruments.  However, certain stock options were issued in the fiscal years
ended August 31, 1995 and 1994 under a nonqualified stock option plan at an
exercise price below market value.  The difference between the exercise price
and the market value of these securities has been included in general and
administrative expense in the fiscal years ended August 31, 1995 and 1994, and
as an addition to equity.

     Income Taxes -- Palatin and its subsidiaries intend to file consolidated
federal and combined state income tax returns.  Palatin accounts for income
taxes in accordance with Statement of Financial Accounting Standards No. 109
(SFAS 109), "Accounting for Income Taxes."  SFAS 109 requires, among other
things, the use of the liability method in computing deferred income taxes.

     Palatin provides for deferred income taxes relating to timing differences
in the recognition of income and expense items (primarily relating to
depreciation, amortization and certain leases) for financial and tax reporting
purposes.  Such amounts are measured using current tax laws and regulations in
accordance with the provisions of SFAS 109.

     In accordance with SFAS 109, Palatin has recorded valuation allowances
against the realization of its deferred tax assets.  The valuation allowance
is based on management's estimates and analysis, which includes tax laws which
may limit Palatin's ability to utilize its tax loss carryforwards.

     Net Loss per Common Share -- Net loss per common share is calculated
based upon the weighted average number of shares of Common Stock, on an as if
converted basis, outstanding during each period.  All options and warrants
were excluded in the calculation of weighted average shares outstanding since
their inclusion would have had an anti-dilutive effect.

     Financial Statement Presentation -- Certain amounts in the accompanying
consolidated financial statements have been reclassified and certain notes have
been modified from previous financial statements to clarify disclosure.

     Use of Estimates -- The preparation of consolidated financial statements
in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amount
of assets and liabilities and disclosure of contingent assets and liabilities
at the date of the consolidated financial statements and the reported amounts
of revenues and expenses during the reporting period.  Actual results could
differ from those estimates.

     New Pronouncements -- The Financial Accounting Standards Board has issued
Statement of Financial Accounting Standards No. 123 (SFAS 123), "Accounting
for Stock-Based Compensation."  SFAS 123 recommends changes in accounting for
employee stock-based compensation plans, and requires certain disclosures with
respect to these plans.  The disclosures of SFAS 123 will be adopted by


                                  F-12
<PAGE>

Palatin effective July 1, 1996.  Management has not determined the effect of
this pronouncement on the Company's financial statements.

     Fair Value of Financial Instruments -- Statement of Financial Accounting
Standards No. 107 (SFAS 107), "Disclosures about Fair Value of Financial
Instruments," requires disclosures of fair value information about financial
instruments, whether or not recognized in the balance sheet, for which it is
practicable to estimate the value.  In cases where quoted market prices are
not available, fair values are based on estimates using present value or other
valuation techniques.  These techniques are significantly affected by the
assumptions used, including discount rate and estimates of future cash flows. 
In that regard, the derived fair value estimates cannot be substantiated by
comparison to independent markets and, in many cases, could not be realized in
immediate settlement of the instrument.  SFAS 107 excludes certain financial
instruments and all non-financial instruments from its disclosure
requirements.  Accordingly, the aggregate fair value amounts presented do not
represent the underlying value of Palatin.

     The following methods and assumptions were used by Palatin in estimating
its fair value disclosures for financial instruments:  the carrying amount
reported on the balance sheet approximates the fair value for cash, short-term
borrowings and current maturities of long-term debt; and the fair value for
Palatin's fixed rate long-term debt is estimated based on the current rates
offered to Palatin for debt of the same remaining maturities.  Based on the
above, the amount reported on the balance sheet approximates the fair value.

(3)   RELATED PARTY TRANSACTIONS:

     Castle Transaction -- During the fiscal year ended August 31, 1995,
RhoMed encountered serious liquidity and working capital deficiencies.  As a
result, effective April 1995, RhoMed entered into a letter of intent with The
Castle Group Ltd. ("Castle"), a company controlled by Lindsay A. Rosenwald,
M.D. ("Dr. Rosenwald"), under which Castle agreed to arrange for a line of
credit of up to $300,000 to finance ongoing operations; agreed to arrange for
future financings; and RhoMed agreed to sell to Castle or its designees, for
$4,000 consideration paid, 4,000,000 shares of RhoMed Series A Preferred Stock
(equivalent to 1,867,809 shares of Common Stock).  At the time the letter of
intent was entered into with Castle, RhoMed was insolvent and its equity had
nominal value; accordingly, the sale of RhoMed Series A Preferred Stock to
Castle or its designees was recorded at the nominal $4,000 consideration paid. 
The issuance of RhoMed Series A Preferred Stock to designees of Castle was
consummated on October 25, 1995.  This resulted in Dr. Rosenwald and his
designees obtaining majority ownership and control of RhoMed.  Pursuant to the
letter of intent, Castle provided a $300,000 line of credit.  RhoMed borrowed
up to the maximum under the line of credit and, at August 31, 1995, had
$23,286 outstanding thereunder, which was paid in September, 1995.  The
average interest rate for the line of credit was 10.90%, and the average
balance outstanding was $191,549.

     Dr. Rosenwald is the Chairman of Paramount Capital, Inc. ("Paramount"),
which served as placement agent for RhoMed as set forth below.  Commencing
July 24, 1995, two of the then three members of the Board of Directors of
RhoMed were employees of entities controlled by Dr. Rosenwald (the "Interested
Directors").  These Interested Directors may have benefited, directly or
indirectly, from the payment of commissions and expenses, and the issuance of
warrants, to Paramount and affiliates.  On July 28, 1995, RhoMed's Board of
Directors approved an offering of Senior Bridge Notes and Class A Warrants
(the "Class A Offering") (see Note 7), for which Paramount served as placement
agent.  Because the Interested Directors could be deemed to have a direct or
indirect interest in a transaction involving a potential conflict of interest
with RhoMed (a "Conflict Of Interest Transaction") contemplated under certain
terms of the Class A Offering, the transaction was ratified by disinterested


                                   F-13
<PAGE>


stockholders on August 15, 1995.  In the Class A Offering, investment funds
managed by a company of which Dr. Rosenwald is president purchased Senior
Bridge Notes with a face value of $100,000, and Class A Warrants to purchase
300,000 shares of RhoMed common stock at $.01 per share (equivalent to 55,299
shares of Common Stock at $.05 per share). 

     On November 27, 1995, RhoMed's Board of Directors approved an offering of
Senior Bridge Notes and Class B Warrants (the "Class B Offering") (see Note
7), for which Paramount served as placement agent.  Because certain terms of
the Class B Offering could also be deemed to be a Conflict of Interest
Transaction, the Interested Directors recused themselves from voting on the
matter, and the Class B Offering was approved by the two disinterested
directors.  In the Class B Offering, investment funds managed by a company of
which Dr. Rosenwald is president purchased Senior Bridge Notes with a face
value of $100,000, and Class B Warrants to purchase 100,000 shares of RhoMed
common stock at an adjusted exercise price of $.125 per share (equivalent to
18,433 shares of Common Stock at $.68 per share). 

     On March 4, 1996, the Board of Directors approved an offering of common
stock (the "Common Stock Offering") (see Note 10), and authorized an offering
committee of the Board of Directors, consisting of the two disinterested
directors, to determine the placement agent for the Common Stock Offering. 
The selection of Paramount as placement agent was approved by the
disinterested directors, who concluded that alternative means of financings
were not available to RhoMed on terms more favorable than the Common Stock
Offering.  The price per share of RhoMed common stock in the Common Stock
Offering of $.25 was determined through negotiations between RhoMed and
Paramount.  On May 14, 1996, the Board of Directors approved an increase in
the Common Stock Offering, on which the Interested Directors recused
themselves, and which was approved by the two disinterested directors.  In the
Common Stock Offering, investment funds managed by a company of which Dr.
Rosenwald is president purchased 7,002,000 shares of RhoMed common stock at
$.25 per share (equivalent to 1,290,696 shares of Common Stock at $1.36 per
share).

     Accrued Compensation -- At June 30, 1996 and August 31, 1995, RhoMed owed
employees approximately $78,000 and $171,000, respectively, for accrued and
unpaid compensation and related benefits.  These amounts do not accrue
interest and are included in accrued compensation in the accompanying
consolidated financial statements.  All such amounts are expected to be paid
in fiscal year 1997.

     Other Transactions -- There have been certain transactions between
Palatin and certain related parties which have resulted in the exchange of
assets or services for equity securities (see Note 10).
 
     Management of Palatin believes that the terms of the transactions and the
agreements described above are on terms at least as favorable as those which
it could otherwise have obtained from unrelated parties.

                                       =============         ============

(5)  INTANGIBLES:

     Palatin has obtained 11 United States (U.S.) patents and corresponding
international applications have been issued or are pending in selected
countries on a majority of issued U.S. patents.  Palatin has applications
pending for 17 additional U.S. patents, the majority of which have pending
international counterparts in selected countries.  Palatin has received
Notices of Allowance, and has paid issue fees, on certain pending U.S. patent
applications.

     Based on an evaluation by the new President and Chief Executive Officer
of RhoMed and his new management team (see Note 9) of products in development
and determination of the likelihood of product development and
commercialization, intangible assets relating to patents not being utilized
for products in active development were written-off to expense.  Historical
costs in each patent were used to determine the total write-off to expense of
$259,334.

     Palatin has assigned its interest in several patents to secure long-term
financing (see Note 6).

(6)  LONG-TERM FINANCING:

     Palatin has a long-term financing agreement with Aberlyn Holding Co.,
Inc., and its affiliates (collectively "Aberlyn").  Aberlyn has, in a series
of transactions, loaned to Palatin approximately $1,800,000, secured by
certain of Palatin's patents, intellectual property and equipment.  Certain
fees and costs related to the borrowings have been deferred as intangible
assets and are being amortized over the remaining terms of the arrangement
using the effective interest method.  The agreement requires the accrual of
certain interest as payable before it is earned; therefore, at any time before
the scheduled payoff, the recorded long-term liability will be less than the
total amount payable to settle the obligation.

     Palatin is obligated, at June 30, 1996, to make monthly payments to
Aberlyn of $20,000 from June 1, 1996 through May 1, 1997, and payments of
$91,695 from June 1, 1997 through May 1, 1999.  Payments through May 1, 1997
will be applied to principal only; interest will be accrued during this period
at an annual effective rate of 15% and paid in Palatin's Common Stock.  On
June 24, 1996, RhoMed issued 930,023 shares of RhoMed common stock (equivalent

                                   F-15
<PAGE>

to 171,433 shares of Common Stock) in payment of accrued interest of $324,546
through April 30, 1996, at an immaterial premium of approximately $.10 per
share over the then fair market value of RhoMed common stock.  In addition,
certain warrants held by Aberlyn were terminated, and RhoMed agreed that
Common Stock paid as interest through May 1, 1997, would contain certain
registration rights, and would be valued at the rate of 75% of the per share
offering price for RhoMed's common stock in any offering commencing after the
consummation of the Common Stock Offering, in which the total offering
proceeds exceeds $5,000,000, or in the event no such offering is completed
before April 30, 1997, at the rate of 75% of the average per share closing
price for the twenty trading days immediately preceding April 30, 1997.  The
25% discount to market value of Common Stock will represent additional
interest payable.  However, management does not anticipate the additional
interest will have a material impact on the financial position or operations
of the Company.

     Scheduled principal payments on the long-term financing through fiscal
year 1999 at June 30, 1996, are as follows:

         Years ending June 30,

(7)  SENIOR BRIDGE NOTES:

     The warrants set forth below were initially exercisable for RhoMed common
stock and are so described.  At Note 10 all outstanding warrants, including
all RhoMed warrants, are shown as converted to Common Stock.

     Class A Offering -- On July 28, 1995, the Board of Directors of RhoMed
authorized an offering of up to 40 units at $25,000 per unit, with each unit
consisting of a $25,000 face amount Senior Bridge Note and a Class A Warrant
to purchase 75,000 shares of RhoMed common stock at an exercise price of $.01
per share (the "Class A Offering") (see Note 3).  The nominal exercise price
for the warrants reflected the seriously troubled financial condition of
RhoMed on the date of the transaction, and accordingly no value was assigned
to the Class A Warrants upon issuance.  The Senior Bridge Notes sold in the
Class A Offering bear interest at 1% per month, and are payable, with accrued
interest, one year from the date of issuance.  Class A Warrants are
exercisable at any time, terminate ten years from the date of issuance, have
certain registration rights, and are subject to adjustment in certain
circumstances, including a stock split of, stock dividend on, or a
subdivision, combination or recapitalization of, the Common Stock.  

     All Class A Offering units were purchased, with net proceeds to RhoMed of
approximately $907,000 after payment of the placement agent's commissions and
expenses ($90,000) and offering expenses (approximately $3,000).  Paramount
(see Note 3), served as placement agent for the offering and received (i) a
cash commission equal to 6% of the gross proceeds from the sale of the units,
(ii) a non-accountable expense allowance equal to 3% of gross proceeds and
(iii) placement agent's warrants ("Class A Placement Agent Warrants"), on the

                                    F-16
<PAGE>


same terms as the Class A Warrants, equal to 15% of the Common Stock
underlying the Class A Warrants issued in the Class A Offering. 

     Class B Offering -- On November 27, 1995, the Board of Directors of
RhoMed authorized an offering of up to 7.5 units at $100,000 per unit, with
each unit consisting of a $100,000 face amount Senior Bridge Note and a Class
B Warrant to purchase 100,000 shares of RhoMed common stock at an exercise
price of the lesser of (a) $.25 per share and (b) 50% of the price per share
of common stock in a subsequent equity offering of RhoMed common stock in
which gross proceeds exceed $2,500,000 (the "Class B Offering").  Due to the
seriously troubled financial condition of RhoMed on the date of the
transaction, no value was assigned to the Class B Warrants upon issuance.  On
January 25, 1996, the Board of Directors increased the Class B Offering from
7.5 units to 8.5 units.  The Senior Bridge Notes sold in the Class B Offering
bore interest at 1% per month, and were payable, with accrued interest, at the
earlier of (a) 5 days following the closing of an equity offering of RhoMed's
securities in which gross proceeds exceeded $2,500,000 and (b) 12 months from
the date of issuance.  The Class B Warrants are exercisable at any time,
terminate 5 years from the date of issuance, have certain registration rights,
contain a call provision and are subject to adjustment in certain
circumstances, including a stock split of, stock dividend on, or a
subdivision, combination or recapitalization of, the Common Stock.  

     On February 15, 1996, the purchase of units was completed.  Net proceeds
to RhoMed were $739,500 after payment of the placement agent's commissions and
expenses ($110,500).  Paramount (see Note 3), served as placement agent for
the Class B Offering and received (i) a cash commission equal to 9% of the
gross proceeds from the sale of the units, (ii) a non-accountable expense
allowance equal to 4% of gross proceeds and (iii) placement agent's warrants
("Class B Placement Agent Warrants"), at an exercise price of $.30 per share
but otherwise on the same terms as the Class B Warrants, equal to 5% of the
Common Stock underlying the Class B Warrants issued in the Class B Offering. 
On June 28, 1996, the Class B Offering Senior Bridge Notes with accrued
interest were paid in full.

(8)  NOTES PAYABLE TO STOCKHOLDERS:

     At June 30, 1996 and August 31, 1995, notes payable to stockholders
consisted of four ten year notes totaling $80,000 plus interest accrued
thereon.  These notes were issued as part of a combined stock and debt
offering during the fiscal year ended August 31, 1992 (see Note 10).  Each
note is a promissory note from RhoMed to the purchaser in the face amount of
$20,000, bearing interest at 10% per year, accruing annually.  Principal and
interest on the notes becomes due and payable on the earlier of (i) July 31,
2002, or (ii) 30 days after RhoMed, or its successor, receives net proceeds
from a public offering of its common stock of at least $5,000,000 or (iii) 30
days after the end of a fiscal year in which, as reflected on the audited
financial statements of RhoMed or its successor, RhoMed or its successor has
net assets of at least $5,000,000 or net income of at least $5,000,000.  The
notes had a provision providing for conversion into common stock on the basis
of one share of stock for each $1.50 of principal and accrued interest.  As a
result of the Merger, there is no longer a right to convert.

(9)   COMMITMENTS AND CONTINGENCIES:

     Leases -- Palatin leases certain of its facilities and equipment under
noncancellable operating leases.  The lease on the facility in Albuquerque,
New Mexico expires on December 31, 1996.  Minimum future annual lease payments


                                    F-17
<PAGE>

at June 30, 1996, are approximately $55,000 in fiscal year 1997, and
approximately $12,000 to $21,000 per year thereafter until fiscal year 2001. 
Certain leases have been personally guaranteed by one or more former officers
of RhoMed.  

     Product Liability -- The testing, marketing and sale of human health care
products entails an inherent risk of allegations of product liability. 
Palatin does not currently have product liability insurance coverage.

     Restructuring Charge -- In conjunction with Palatin's decision to
consolidate and relocate its research and development facilities and executive
offices in the New Jersey area, Palatin established a restructuring charge of
$284,000.  The restructuring charge represents severance costs of $115,000 and
facility closing expenses of $169,000.  It is anticipated that eight research
and development and administration and management employees will be severed;
through June 30, 1996, five employees had been severed.  Facility closing 
expenses consist primarily of costs related to lease termination and fixed 
asset disposals.  Included in accrued expenses at June 30, 1996, is $257,152 of
remaining restructuring charge.

     Commitments -- On November 27, 1995, the Board of Directors of RhoMed
ratified an employment agreement (the "Employment Agreement") with Edward J.
Quilty ("Mr. Quilty") to serve as President and Chief Executive Officer of
RhoMed.  Pursuant to the Agreement, RhoMed agreed to grant Mr. Quilty an
option to acquire such number of shares of common stock as equal a 10% fully
diluted equity interest in RhoMed at an exercise price of $.01 per share,
which option vests in 36 equal increments on each of the first 36 monthly
anniversaries of the commencement of Mr. Quilty's employment with RhoMed, and
may be accelerated or terminated in part on the happening of certain events
(the "Initial Option").  The Agreement further provides for anti-dilutive
options, pursuant to which Mr. Quilty will be issued  options to acquire the
number of shares that, when aggregated with the shares issuable pursuant to
the Initial Option, equal not less than 3.75% of the shares of common stock of
RhoMed.  The Agreement is for an initial period of one year, with automatic
one year extensions, and provides that, on certain termination events, the
portion of the options that would otherwise have terminated without vesting,
vest and are exercisable upon termination, and also provides for specified
termination pay. 

     Palatin is obligated under two consulting agreements to make payments of
$157,000 in fiscal year 1997 and $76,500 in fiscal year 1998.

     Legal Proceedings -- Palatin is subject to various claims and litigation
in the ordinary course of its business, including patent proceedings. 
Management believes that the outcome of such legal proceedings will not have a
material adverse effect on Palatin's financial position or future results of
operation.

(10) STOCKHOLDERS' EQUITY (DEFICIT):

     Palatin Authorized Shares -- The authorized capital stock of Palatin at
the time of the Merger consisted of 10,000,000 Common Stock shares and
2,000,000 shares of preferred stock, $.01 par value per share.  On July 19,
1996, Palatin's Certificate of Incorporation was amended to, among other
things, increase the number of shares of authorized Common Stock to 25,000,000
and to effect a 1-for-10 reverse split of the Common Stock.  The consolidated
financial statements have been adjusted to reflect the amendment to the
Certificate of Incorporation.

     RhoMed Authorized Shares -- By Articles of Amendment approved by RhoMed's
stockholders on April 4, 1996 and filed April 10, 1996, RhoMed amended its
Articles of Incorporation to increase its


                                   F-18 
<PAGE>

authorized common stock from 40,000,000 to 60,000,000 shares with no par 
value. By Articles of Amendment approved by RhoMed's stockholders on 
May 24, 1996 and filed June 7, 1996, RhoMed amended its Articles of 
Incorporation to increase its authorized common stock from 60,000,000 to 
90,000,000 shares with no par value. RhoMed has 10,000,000 shares of 
authorized preferred stock, no par value.

        Stock Transactions -- On March 4, 1996, the Board of Directors of
RhoMed authorized an offering of up to 40 units at $100,000 per unit, with
each unit consisting of 400,000 shares of RhoMed common stock at a purchase
price of $.25 per share (the "Common Stock Offering") (equivalent to 73,733
shares per unit at a purchase price of $1.36 per Palatin Common Stock share).
On May 14, 1996, the Board of Directors authorized an increase in the Common
Stock Offering of up to 100 units. Paramount served as placement agent for the
Common Stock Offering and received (i) a cash commission equal to 9% of the
gross proceeds from the sale of the units, (ii) a non-accountable expense
allowance equal to 4% of gross proceeds and (iii) placement agent's warrants
("Stock Offering Placement Agent Warrant"), equal to 10% of the common stock
issued in the Common Stock Offering, at an exercise price of $.30 per RhoMed
common stock share (equivalent to $1.63 per Palatin Common Stock share), which
are freely exercisable and terminate ten years from the date of issuance, have
certain registration rights, and are subject to adjustment in certain
circumstances. On June 24, 1996, RhoMed terminated the Common Stock Offering.
RhoMed sold 96.454 units, realizing net proceeds of approximately $8,391,000,
and issued 38,581,600 shares of RhoMed common stock (equivalent to 7,111,846
shares of Common Stock).

        On June 24, 1996, and pursuant to the Merger, certain stockholders of
Interfilm prior to the Merger and third parties purchased 3,000,000 shares of
RhoMed common stock at a purchase price of $.25 per share, with net proceeds
to RhoMed of approximately $748,000 (equivalent to 552,997 shares of Common
Stock at a purchase price of $1.36). Also, and pursuant to the Merger,
warrants to purchase 1,500,000 shares of RhoMed common stock at an exercise
price of $.40 were issued to certain stockholders of Interfilm prior to the
Merger and third parties ("Merger Warrants") (equivalent to 276,499 shares of
Common Stock at an exercise price of $2.17). The Merger Warrants are
exercisable at any time, terminate four years from the date of issuance, have
certain registration rights, contain a call provision and are subject to
adjustment in certain circumstances.

        In the ten months ended June 30, 1996, RhoMed issued 124,525 shares of
RhoMed common stock (equivalent to 22,954 shares of Common Stock) in exchange
for services, and Palatin issued 103,017 shares of Common Stock in exchange
for services. In addition, RhoMed has issued stock for accrued interest, and
Palatin is obligated to issue additional stock in payment of accrued interest
(see Note 6).

        RhoMed commenced a private offering of preferred stock in fiscal year
1994, and a private offering of units consisting of RhoMed common stock and
common stock warrants in fiscal year 1995, both of which were terminated
without having raised the minimum required for closing. Stock issuance costs
incurred in connection with both offerings were expensed to operations in the
fiscal year in which such costs were incurred.

        In February 1993, RhoMed issued a private offering memorandum for the
sale of securities, consisting of units of 10,000 shares of RhoMed common
stock for $10,000 per unit ($1.00 per share). RhoMed sold 58.4 units,
realizing net proceeds of approximately $577,000.

     In September 1992, RhoMed issued a private offering memorandum for the
sale of securities, consisting of units of 33,333 shares of RhoMed common
stock for $25,000 per unit ($.75 per share).  RhoMed sold 8 units, realizing
net proceeds of approximately $191,000.  

                                   F-19 

<PAGE>


     In December 1991, RhoMed issued a private offering memorandum for the
sale of units consisting of 26,289 shares of RhoMed common stock and a $20,000
note (see Note 8).   Four units were sold for $25,000 per unit.

     RhoMed common stock issuance prices represented market value of the
RhoMed common stock on the date of issuance.

     Outstanding Stock Purchase Warrants -- At June 30, 1996, Palatin had the
following warrants outstanding, all of which are currently exercisable except
11,111 warrants included in "Other Warrants."  Each warrant is restated as

The Class B Offering and Merger Warrants contain provisions providing for
termination of the warrant if not exercised following notice of specified per
share trading prices.

     Palatin Stock Option Plans -- Palatin had, prior to the Merger, adopted
its 1993 Equity Incentive Plan, pursuant to which options for 26,750 Common
Stock shares, calculated on a post-reverse stock split basis, were granted and
outstanding at June 30, 1996.  Palatin does not intend to issue any new
options under the 1993 Equity Incentive Plan.

     RhoMed Stock Option Plans -- RhoMed has 4 stock option plans, with
options granted thereunder constituting RhoMed Derivative Securities which,
pursuant to the Merger, were automatically converted into rights upon exercise
to receive Common Stock in the same manner in which the shares of RhoMed
common stock were converted.

     Two RhoMed stock option plans are qualified "incentive stock option"
plans under the Internal Revenue Code, for which 8,250,000 shares of RhoMed
common stock were reserved.  The other plans are nonqualified stock option
plans, for which 3,250,000 shares of RhoMed common stock were reserved. 
Palatin does not intend to issue any new options under the RhoMed stock option
plans.

        The table below presents options in RhoMed common stock, with
conversion to Common Stock shown as "Restated to Palatin Options." The
"Outstanding" and "Exercisable" as of June 30, 1996, are stated as Common
Stock. Information related to stock option activity under these plans for the
period from inception to June 30, 1996 is as follows:

(11)    GRANTS, CONTRACTS AND ROYALTIES:

        Pursuant to contract with the New Mexico Research and Development
Institute to develop products for medical research and diagnostic imaging, for
which all work has now been completed, the State of New Mexico earns (i) a 2%
royalty on gross revenues for products developed under the contract and
manufactured in New Mexico and (ii) a 5% royalty on products manufactured
outside New Mexico, subject to maximum repayment limits over specified time
frames.

        RhoMed applies for and has received grants and contracts under the
Small Business Innovative Research (SBIR) program and other federally funded
grant and contract programs. Since inception, approximately $2,526,000 of
RhoMed's revenues have been derived from federally or state funded grants and
contracts. Under federal grants and contracts, there are no royalties or other
forms of repayment; however, in certain limited circumstances the government
can acquire rights to technology which is not being commercially exploited.
Most contract costs, including indirect costs, are subject to audit and
adjustment by negotiation with government representatives.

     RhoMed also engages in contract development work with private sector
companies, both foreign and domestic.  From inception to August 31, 1995,
RhoMed's contract revenues from such private sector companies are
approximately $335,000.

     RhoMed has solicited and performed cooperative research and development
agreements with various national laboratories of the Department of Energy,
which did not involve any payment of funds to the Department of Energy or its
contractors by RhoMed and were cancelable by RhoMed upon less than six month's
notice to the relevant contractor.

(12) LICENSING AGREEMENTS:

     RhoMed entered into a license agreement, effective November 2, 1992, with
Sterling Winthrop, Inc., a major pharmaceutical company ("Sterling"), under
which RhoMed granted to Sterling (i) a non-exclusive license to certain
patented radiolabeling technology for imaging uses and (ii) an option to
acquire a license on similar terms for therapeutic uses.  The license
agreement is renewable annually and provides for certain license fee payments
to RhoMed together with milestone payments on product development and
percentage of sales production royalties.  During the fiscal years ended

                                     F-21
<PAGE>

August 31, 1995 and 1994, RhoMed received $50,000 in royalties and option
payments under the license agreement.  During the fiscal year ended August 31,
1994, the license agreement was assigned by Sterling to Burroughs Wellcome
Co., a major pharmaceutical company, in conjunction with the purchase of
certain assets of Sterling by Burroughs Wellcome Co.  Concurrently with
entering into the license agreement, RhoMed entered into a development
agreement, which expired December 31, 1993, with Sterling, under which RhoMed
performed specified product development services for $125,000, of which
$25,000 is included in grant and contract revenue for the fiscal year ended
August 31, 1994. 

     RhoMed entered into a license agreement, effective May 1, 1992, with
Rougier Bio-Tech Limited, a foreign biotechnology concern ("Rougier"), under
which RhoMed granted Rougier an exclusive license to certain patented
radiolabeling technology for a defined field-of-use.  The agreement, which is
for the life of the patents and is renewable annually, provides for license
fee payments to RhoMed and percentage of sales production royalties with a
minimum annual royalty.  Under this agreement, $7,500 of royalties and fees
were paid to RhoMed in the fiscal year ended August 31, 1995. 

(13) INCOME TAXES:

     Effective September 1, 1993, RhoMed adopted Statement of Financial
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes."  Prior
to 1993, RhoMed accounted for income taxes following the provisions of
Accounting Principles Board Opinion No. 11.

     RhoMed has had no income tax expense or benefit since inception because
of operating losses.  Deferred tax assets and liabilities are determined based
on the estimated future tax effect of differences between the financial
statements and tax reporting basis of assets and liabilities, given the
provisions of the tax laws.  A valuation allowance for the net deferred tax
assets has been recorded at June 30, 1996, based on the weight of evidence
that the deferred tax assets exceed the likely reversal of deferred tax
liabilities and likely taxable income.  The difference between the expected
benefit of the federal tax rate of 34% and the actual benefit of zero is due
to this valuation allowance.  Significant components of deferred tax assets
and liabilities are as follows:

        The Tax Reform Act of 1986 imposes limitations on the use of net
operating loss carryforwards if certain stock ownership changes occur. As a
result of the change in majority ownership relating to the Castle transaction
(see Note 3), the Common Stock Offering (see Note 10) and the Merger (see Note
1), under Internal Revenue Code Section 382, RhoMed most likely will not be
able to utilize its net operating loss carryforwards after the dates of
ownership change. Thus, Palatin most likely will not be able to realize the
benefit of any or all of RhoMed's net operating loss carryforwards in the
future.

        Furthermore, due to the Merger, Palatin applied to the Internal
Revenue Service to change its year end to June 30 from December 31. Internal
Revenue Service approval of this change is still pending.

        Income tax returns for RhoMed for the years ended August 31, 1995 and
1994 have not been filed; however, management believes that since there is no
tax liability, there will be no material adverse effect on Palatin.

(14)    COMPARISON WITH TEN MONTHS ENDED JUNE 30, 1995:

        As noted above (see Note 1), Palatin changed its fiscal year end to
June 30. Therefore, the following June 30, 1995, selected financial
information, adjusted to reflect the amendment to the Certificate of 
Incorporation of Palatin as if it had been filed on June 30, 1995, and as 
if the Merger had been consummated on June 25, 1995, is presented
for comparative purposes only (unaudited):

                       (A Development Stage Enterprise)
             Notes to Consolidated Financial Statements (Unaudited)
               For the Nine Months Ended March 31, 1997 and 1996

(1)   NATURE OF BUSINESS

      Through its wholly-owned subsidiary RhoMed Incorporated ("RhoMed"),
Palatin Technologies, Inc. (the "Company") is a development-stage
biopharmaceutical company dedicated to developing and commercializing products
and technologies for diagnostic imaging, cancer therapy and ethical drug
development utilizing peptide, monoclonal antibody and radiopharmaceutical
technologies.  The Company was incorporated under the laws of the State of
Delaware on November 21, 1986.  Since June 25, 1996, the effective date of the
merger (the "Merger") of a wholly-owned subsidiary of the Company with and
into RhoMed, all outstanding shares of RhoMed equity securities were exchanged
for the Company's common stock, $.01 par value per share (the "Common Stock"). 
The business of RhoMed represents the on-going business of the Company.

     As a result of the Merger, RhoMed became a wholly-owned subsidiary of the
Company, with the holders of RhoMed preferred stock and RhoMed common stock
(including the holders of "RhoMed Derivative Securities" as hereafter defined)
receiving an aggregate of approximately 96% interest in the equity securities
of the Company on a fully-diluted basis.  Additionally, all warrants and
options to purchase common stock of RhoMed outstanding immediately prior to
the Merger (the "RhoMed Derivative Securities"), including without limitation,
any rights underlying RhoMed's qualified or nonqualified stock option plans,
were automatically converted into rights upon exercise to receive the
Company's Common Stock in the same manner in which the shares of RhoMed common
stock were converted.  Since the former stockholders of RhoMed retained more
than a 50% controlling interest in the surviving company (Palatin
Technologies, Inc.), the Merger was accounted for as a reverse merger.  The
historical financial statements prior to June 25, 1996, are those of RhoMed,
except that the net loss per common share has been stated on an as if
converted basis.

     Since its inception, RhoMed has devoted substantially all of its efforts
and resources to the research and development of its technology.  RhoMed has
experienced operating losses in each year since its inception and, as of March
31, 1997, the Company, including its wholly-owned subsidiary RhoMed, had a
deficit accumulated during the development stage of $11,658,444.  The Company
expects to incur additional operating losses over the next several years and
expects cumulative losses to increase as the Company's research and
development and clinical testing efforts continue and expand.  The ultimate
completion of the Company's development projects is contingent upon a number
of factors, including the successful completion of technology and product
development, obtaining required regulatory approvals and additional financing
and, ultimately, successfully commercializing its products and achieving
profitable operations.

(2)  BASIS OF PRESENTATION

     The accompanying financial statements have been prepared by the Company
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission (the "Commission").  Certain information and footnote
disclosure normally included in the Company's audited annual financial
statements has been condensed or omitted in the Company's interim financial
statements.  In the opinion of the Company, these financial statements contain
all adjustments (consisting of only normal recurring adjustments) necessary to
present fairly the financial position of the Company as of March 31, 1997 and
June 30, 1996, and the results of operations for the three and nine month
periods ended March 31, 1997 and 1996 and cash flows for the nine months ended
March 31, 1997 and 1996, and for the period from inception (January 28, 1986)
to March 31, 1997.  The results of operations for the interim period may not
necessarily be indicative of the results of operations expected for the full
year, except that the Company expects to incur a significant loss for the
fiscal year ended June 30, 1997.

     The accompanying financial statements and the related notes should be
read in conjunction with the Company's audited financial statements for the
ten months ended June 30, 1996 and the fiscal years ended August 31, 1995 and
1994 filed with the Company's Form 10-KSB for the transition period from
September 1, 1995 to June 30, 1996. 

(3)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     Research and Development Costs -- The costs of research and development
activities are expensed as incurred.

     Net Loss per Common Share -- Net loss per common share is calculated
based upon the weighted average number of shares of Common Stock, on an as if
converted basis, outstanding during each period.  All options and warrants
were excluded in the calculation of weighted average shares outstanding since
their inclusion would have had, in the aggregate, an anti-dilutive effect. 

     In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standard No. 128 (SFAS 128), "Earnings per
Share."  The statement is effective for financial statements for periods
ending after December 15, 1997, and changes the method in which earnings per
share will be  determined.  Adoption of this statement by the Company will not
have a material impact on earnings per share. 

     Revenue Recognition -- The Company recognizes revenue as follows: grants
and contracts - at the time such related expenses are incurred in compliance
with contractual terms; license fees and royalties - ratably over the term of
the license or royalty agreement; and sales - upon shipment of the product.

     Use of Estimates -- The preparation of consolidated financial statements
in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amount
of assets and liabilities and disclosure of contingent assets and liabilities
at the date of the consolidated financial statements and the reported amounts
of revenues and expenses during the reporting period.  Actual results could
differ from those estimates.

(4)  SENIOR BRIDGE NOTES:

     On July 28, 1995, the Board of Directors of RhoMed authorized an offering
of up to 40 units at $25,000 per unit, with each unit consisting of a $25,000
face amount Senior Bridge Note and a Class A Warrant to purchase 75,000 shares
of RhoMed common stock (equivalent to 13,285 shares of Common Stock) at an
exercise price of $.01 per share (the "Class A Note and Warrant Offering"). 
The Senior Bridge Notes sold in the Class A Note and Warrant Offering (the
"Senior Bridge Notes") bore interest at 1% per month, and were payable, with
accrued interest, one year from the date of issuance.  All of the 40 Class A
Note and Warrant Offering units were purchased with proceeds prior to
commissions and expenses of $1,000,000.  In August and September of 1996, the
Senior Bridge Notes sold in the Class A Note and Warrant Offering were repaid
in full, totaling $1,000,000 of principal and $120,000 of accrued interest.

(5)  SERIES A PREFERRED STOCK:

     On December 2, 1996, the Company commenced an offering of units of Series
A Preferred Stock (the "Series A Offering") at a price of $100,000 per unit,
with each unit consisting of 1,000 shares of Series A Preferred Stock.  As of
March 31, 1997,  the Company had sold 30.63 units, representing 30,630 shares
of Series A Preferred Stock, for net proceeds to the Company of $2,680,591,
after deducting commission and other expenses of the Series A Preferred Stock
offering.  The final closing on the Series A Offering was effective as of May
9, 1997, with the Company having sold an aggregate total of 137.78 units,
representing 137,780 shares of Series A Preferred Stock, for gross proceeds of
$13,778,000 and net proceeds to the Company of approximately $11,800,000,
after deducting commission and other expenses of the Series A Offering.

     Each share of Series A Preferred Stock is convertible, at the option of
the holder thereof, into shares of Common Stock at a conversion price of
$1.24.  The $1.24 represents a discount of 15% to the average closing bid
price of the Common Stock for the twenty (20) consecutive trading days
immediately preceding the final closing.  The 15% discount has been reflected
in the Company's consolidated statement of operations as a dividend to Series
A Preferred Stock of $540,529.  The Series A Preferred Stock also contains a
reset mechanism (see Part II, Item 2, "Change in Securities").  The Series A
Preferred Stock may be mandatorily converted by the Company, if, commencing
May 9, 1998, the closing bid price of the Common Stock exceeds 200% of the
then applicable conversion price for at least twenty (20) trading days in any
thirty (30) consecutive trading day period ending three (3) days prior to the
date of conversion.

     In the event that the Company does not, by February 3, 1998, increase its
authorized capital to at least that number of shares of Common Stock necessary
for issuance upon exercise of all Series A Preferred Stock sold in the Series
A Offering, the Company has agreed that the holders of Series A Preferred
Stock shall be entitled, at the option of each holder to either:  (i) require
the Company to repurchase all shares of Series A Preferred Stock then held by
such holder at $100.00 per share of Series A Preferred Stock, or (ii) require
the Company to purchase at fair market value that portion of the shares which
would have been issuable to the holder upon conversion but which the Company
was unable to issue due to the lack of authorized and reserved shares of
Common Stock.  The fair market value per share of Common Stock shall be paid
in cash, or, if the Company does not have sufficient cash, then with secured
demand notes, the fair market value shall mean the closing bid price per share
of the Common Stock as quoted on the OTC Bulletin Board for the trading day
immediately preceding the conversion.



                             F-30
<PAGE>


     As of March 31, 1997, the Company had sufficient Common Stock to convert
all Series A Preferred Stock outstanding.  If the Company does not have a
sufficient number of authorized shares of Common Stock available for
conversion of all outstanding Series A Preferred Stock prior to the issuance
of the Company's financial statements for the fiscal year ending June 30,
1997, the Company will, as appropriate, classify the amount of Series A
Preferred Stock in excess of Common Stock available for conversion outside of
stockholders' equity.

     The securities offered in the Series A Offering have not been registered
under the Securities Act of 1933, as amended, and may not be offered or sold
in the United States absent registration or an applicable exemption from
registration requirements.  The Company agreed to file, no later than July 8,
1997, a registration statement under the Securities Act to permit resales
of the Common Stock issuable upon conversion of the Series A Preferred Stock.
The Company is in the process of preparing such registration statement and 
intends to file it as soon as practicable.

(7)  COMMITMENTS AND CONTINGENCIES:

     Leases -- The Company leases certain of its facilities and equipment
under noncancellable operating leases.  In October 1996, the  lease on the
facility in Albuquerque, New Mexico was extended from March 31, 1997 until
August 31, 1997, and in March 1997, the lease was amended to provide for
optional extensions through December 31, 1997.  In March 1997, the Company
entered into a ten-year lease on research and development facilities in
Edison, New Jersey, with the lease term expected to commence in July 1997. 
Minimum future lease payments escalate from approximately $116,000 per year to
$200,000 per year after the fifth year of the lease term.  The lease will
expire in fiscal year 2007.

     Merger Costs -- In conjunction with the Merger which occurred on June 25,
1996, costs of $525,000 were charged to operations for the ten months ended
June 30, 1996.  With no additional Merger costs anticipated, the remaining
accrual of $17,419 was written off as of March 31, 1997.

     Restructuring Charge -- In conjunction with the Company's decision to
consolidate and relocate its research and development facilities and executive
offices in the New Jersey area, the Company established a restructuring charge
of $284,000.  The restructuring charge to date represents severance costs of
$115,000 and facility closing expenses of $169,000.  Through March 31, 1997,
eight research and development and administration and management employees had
been severed.  Facility closing expenses consist primarily of costs related to
lease termination and fixed asset disposals.  Included in accrued expenses at
March  31, 1997, is $142,736 of remaining restructuring charge.

         PART II.  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT



Item 24.  Indemnification of Directors and Officers.

         Section 145 of the Delaware  General  Corporation  Law provides  that a
corporation  may  indemnify any person who was or is a party or is threatened to
be  made a  party  to any  threatened,  pending  or  completed  action,  suit or
proceeding,  whether civil, criminal,  administrative or investigative by reason
of the fact  that he is or was a  director,  officer,  employee  or agent of the
corporation, or serving at the request of the corporation in similar capacities,
against expenses (including attorneys' fees), judgments, fines, and amounts paid
in settlement  actually and reasonably  incurred by him in connection  with such
action,  suit or  proceeding  if he  acted  in good  faith  and in a  manner  he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation,  and,  with respect to any criminal  action or  proceeding,  had no
reasonable  cause to believe his conduct was unlawful.  In the case of an action
or suit by or in the right of the corporation,  no indemnification shall be made
with  respect to any claim,  issue or matter as to which such person  shall have
been adjudged to be liable to the corporation unless and only to the extent that
the court having  jurisdiction  shall  determine  that such person is fairly and
reasonably entitled to indemnity.

         Article V,  Section 3 of the  Company's  Certificate  of  Incorporation
provides  that  to  the  fullest  extent   permitted  by  the  Delaware  General
Corporation  Law, no director of the Company shall be  personally  liable to the
Company or its  stockholders for monetary damages for breach of a fiduciary duty
as a director.

         Article VI of the Company's Certificate of Incorporation  provides that
the Company shall make the  indemnification  permitted  under Section 145 of the
Delaware General  Corporation Law, as summarized above, but only (unless ordered
by a court)  upon a  determination  by a majority  of a quorum of  disinterested
directors,  by  independent  legal  counsel  in a  written  opinion,  or by  the
stockholders,  that the  indemnified  person has met the applicable  standard of
conduct.  Article VI further  provides that the Company may advance expenses for
defending  actions,  suits or proceedings  upon such terms and conditions as the
Company's  Board of  Directors  deems  appropriate,  and that  the  Company  may
purchase  insurance on behalf of indemnified  persons whether or not the Company
would have the power to indemnify  such persons  under  Section 145 the Delaware
General Corporation Law.

         The Company's  Bylaws contain  substantially  the same  indemnification
provisions as the Company's Certificate of Incorporation, summarized above.

         The Company's  employment  agreement with Edward J. Quilty requires the
Company to indemnify  and advance  expenses to Edward J. Quilty,  the  Company's
Chairman of the Board,  President and Chief  Executive  Officer,  to the fullest
extent permitted under Section 145 of the Delaware General Corporation Law.

         Each of the agreements pursuant to which Selling Stockholders  acquired
Offered  Shares from the Company  provides that the Company will  indemnify each
Selling  Stockholder,  and each Selling  Stockholder will indemnify the Company,
and in some cases the Company's directors, officers and control persons, against
certain  liabilities which might arise from the Offering.  The  indemnifications
may cover  liabilities  arising under the  Securities  Act. The  obligation of a
Selling Stockholder to indemnify the Company or its affiliates is (absent fraud)
limited to liabilities based on

                                 Part II - 1

<PAGE>



written  information which the Selling  Stockholder  provides to the Company for
inclusion in the Registration Statement.

         The Company has obtained a directors' and officers' liability insurance
policy which covers,  among other things,  certain liabilities arising under the
Securities Act.



Item 25.  Other Expenses of Issuance and Distribution.

         The Company will bear all expenses, estimated at $[_________], incurred
in connection  with the  registration of the Offered Shares under the Securities
Act and  qualification or exemption of the Offered Shares under state securities
laws, excluding fees of legal counsel for any Selling Stockholder.  Each Selling
Stockholder  will  pay  all  underwriting   discounts  and  selling  commissions
applicable to the sale of the Selling Stockholder's Offered Shares.

no public solicitation.  Transfer of the Series A Convertible Preferred Stock is
restricted  and the  certificates  representing  Series A Convertible  Preferred

Stock for the  purchaser's own account for investment and not with a view toward

not include Preferred Stock Placement Warrants, described below.

         2. Preferred Stock  Placement  Warrants.  The Company issued  Preferred
Stock  Placement  Warrants to purchase an aggregate of 13,778 shares of Series A
Convertible Preferred Stock to the Placement Agent and/or its designees, as part
of the Placement  Agent's  compensation in connection with the sales of Series A
Convertible  Preferred Stock described above. The Company will receive a nominal
cash price for the Preferred Stock Placement Warrants of $13.78 ($.001 per share
of Series A Convertible Preferred Stock issuable). The Preferred Stock Placement
Warrants  are  exercisable  for a period of five (5) years  starting in November
1997, at a price of $110 per share of Series A Convertible Preferred Stock (110%
of the offering  price of Series A Convertible  Preferred  Stock in the offering
described above), and include a cashless exercise provision. The Company claimed
exemption  under Rule 506 of Regulation D under the Securities  Act. The Company
issued the securities solely to directors, officers, employees, salespersons, or
other affiliates of the Placement Agent (including two accredited  investors who
purchased Series A Convertible  Preferred Stock in the offering described above)
and made no public  solicitation.  Transfer  of the  Preferred  Stock  Placement
Warrants is restricted and the warrant agreements bear a restrictive legend.

sold a total of 96,770  restricted  shares of Common Stock upon  exercise of the
Company's  outstanding Class A Warrants to six exercising  warrant holders.  The
Company  claimed  exemption  under  Section  4(2) of the  Securities  Act, for a
transaction not involving any public  offering.  Before the sales on exercise of
Class A Warrants listed below,  there were 22 holders of Class A Warrants,  each
of whom  purchased  the Class A Warrants  from  RhoMed in a private  offering to
accredited  investors  only, in compliance with Rule 506 of Regulation D. In the
Merger,  the Company  assumed the obligation to issue Common Stock upon exercise
of the Class A Warrants  at  approximately  $.0542 per  share.  Each  exercising
warrant  holder had held the warrant  for more than one year before  exercising.
Transfer  of both the Class A Warrants  and Common  Stock  issued on exercise of
Class  A  Warrants  is  restricted   and  the  warrants  and  the   certificates
representing   Common  Stock  issued  on  exercise  of  Class  A  Warrants  bear
restrictive  legends.  The  Company  sold  the  Common  Stock  directly  to  the
exercising warrant holders, with no discount or commission.

the Company sold 255,641  restricted  shares of Common Stock to Bioquest Venture
Leasing Partnership L.P., the designee of Aberlyn, a creditor of the Company, as
payment in full of $303,171 of accrued  interest  which the Company owed Aberlyn
under a financing arrangement.  The Company claimed exemption under Section 4(2)
of the Securities Act, for a transaction not involving any public offering. This
was a one-time  transaction  negotiated at arm's length  between the Company and
its  largest  creditor.  The  Common  Stock  issued as payment  of  interest  is
restricted and the certificate representing the Common Stock bears a restrictive
legend.  Aberlyn  represented  to the Company that Aberlyn and its designee were
accredited  investors  (as  defined  in  Regulation  D) and that  Aberlyn or its
designee was  acquiring  the stock for its own account and not with a view to or
for sale in connection with any distribution of the Common Stock in violation of
the  Securities  Act. The Company  sold the Common  Stock  directly to Aberlyn's
designee with no discount or commission.

         6. Series A Preferred  Stock issued in connection  with the Merger.  On
June 25,  1996,  in  connection  with the  Merger,  the  Company  issued  40,000
restricted shares of Series A Preferred Stock (not the same series as the Series
A  Convertible  Preferred  Stock  referred to in paragraph 1 of this Item 26) in
exchange for 4,000,000  shares of RhoMed  preferred  stock.  The Company claimed
exemption under Section 3(a)(10) of the Securities Act, for securities issued in
exchange  for  outstanding  securities,  after a hearing on the  fairness of the
terms of the transaction as contemplated in Section 3(a)(10).  On June 12, 1996,
the California  Department of  Corporations  issued a permit for the exchange of
securities in the Merger, following a hearing upon the fairness of the terms and
conditions  of the  exchange  offer.  On July 19,  1996,  the Series A Preferred
Stock, which was uncertificated,  automatically  converted into 1,867,809 shares
of  unrestricted  Common  Stock by  operation of the  Company's  Certificate  of
Incorporation.  The  Merger  exchange  was  solely  stock-for-stock  and did not
involve any cash payments (other than cashing out fractional  shares on issuance
of Common Stock), discounts or commissions.

         7. Series B Preferred Stock issued in connection  with Merger.  On June
25,  1996,  in  connection  with  the  Merger,  the  Company  issued  495,515.51
restricted  shares of Series B Preferred Stock in exchange for 49,558,217 shares
of RhoMed common stock. The Company claimed  exemption under Section 3(a)(10) of
the  Securities   Act,  for  securities   issued  in  exchange  for  outstanding
securities,  after a hearing on the fairness of the terms of the  transaction as
contemplated in Section 3(a)(10). On June 12, 1996, the California Department of
Corporations  issued a permit for the  exchange  of  securities  in the  Merger,
following  a  hearing  upon the  fairness  of the terms  and  conditions  of the
exchange  offer.  On July 19,  1996,  the Series B  Preferred  Stock,  which was
uncertificated,  automatically  converted into 9,133,838  shares of unrestricted
Common Stock by operation of the Company's  Certificate  of  Incorporation.  The
Merger exchange was solely stock-for-stock and did not involve any cash payments
(other  than  cashing  out  fractional  shares on  issuance  of  Common  Stock),
discounts or commissions.

Company issued  5,588.6860985  restricted  shares of Series B Preferred Stock to
the designees of Wharton  Capital  Corp.,  to pay a fee pursuant to an agreement
between  Wharton Capital Corp. and RhoMed.  The Company claimed  exemption under
Section 4(2) of the Securities  Act, for a transaction  not involving any public
offering.   On  July  19,  1996,  the  Series  B  Preferred  Stock,   which  was
uncertificated, automatically converted into 103,017 shares of restricted Common
Stock  by  operation  of  the  Company's   Certificate  of  Incorporation.   The
certificates representing the Common Stock bear restrictive legends. The Company
sold the Series B Preferred Stock directly to Wharton Capital Corp. with no cash

    The Company will:

    (1) File,  during  any  period in which it  offers  or sells  securities,  a
post-effective amendment to this registration statement to:

       (i) Include any prospectus required by Section 10(a)(3) of the Securities
Act;

        (ii) Reflect in the prospectus  any facts or events which,  individually
or together,  represent a fundamental change in the information set forth in the
registration statement.  Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was  registered)  and any deviation  from the low or
high end of the estimated maximum offering range may be reflected in the form of
prospectus  filed  with  the  Commission  pursuant  to Rule  424(b)  if,  in the
aggregate,  the changes in volume and price  represent no more than a 20% change
in the  maximum  aggregate  offering  price  set  forth in the  "Calculation  of
Registration Fee" table in the effective registration statement; and

        (iii) Include any additional or changed material information on the plan
of distribution.

    (2)  For  determining   liability  under  the  Securities  Act,  treat  each
post-effective  amendment  as a new  registration  statement  of the  securities
offered, and the offering of such securities at that time to be the initial bona
fide offering thereof.

    (3) File a post-effective  amendment to remove from  registration any of the
securities that remain unsold at the end of the offering.
